121 Progress Report
North Texas Tollway Authority
State Highway (SH) 121 stretches 26 miles southeast to
northwest, linking the Dallas -Fort Worth Airport and rapidly
growing communities in Collin, Dallas and Denton counties. When
construction is completed, the six main lanes of SH 121 will feature
all- electronic toll collection gantries, increasing mobility, reducing
travel time, fostering economic development and improving
regional air quality.
•
• The North Texas Tollway Authority (NTTA) and the Texas
Department of Transportation (TxDOT) finalized a project
agreement for SH 121 on August 23, 2007. The agreement
authorizes the NTTAto design, build, operate and maintain SH
121 in Collin, Dallas and Denton counties for approximately
50 years, beginning with the opening of Segments 1 and 2 in
fall 2008. TxDOT executed the project agreement on
October 18, 2007 following the Federal Highway
Administration's environmental clearance of a re- evaluation
of Segments 1 -4.
• The NTTA presented a Texas -sized check and made the
required upfront payment to TxDOT and the Regional
Transportation Council of the North Central Texas Council of
Governments on November 30, 2007.
• Most of the required right of way (ROW) for the project
has been acquired by TxDOT, Collin, Dallas and Denton
counties; and the cities of Plano, Frisco, Allen and McKinney.
In October 2007, the NTTA initiated ROW acquisition and
utility coordination services for Segment 4. Segment 5
ROW acquisition, to be funded by TxDOT, will begin after
environmental clearance is received.
• The Allen City Council approved a resolution on January
8, 2008 supporting an updated preliminary design for the
SH 121 interchange with U.S. Highway 75. The council's
resolution notes that the updated design will "improve
mobility and access for residents of the city of Allen as well
as surrounding areas."
• McKinney City Council members approved a similar
resolution on February 5, 2008.
February 13, 2008
• An alternate design concept for the SH 121 interchange
with U.S. 75 (Segment 4) is being discussed with Allen,
Fairview, McKinney and Collin County. An alternate design
for Segment 4 will require environmental re- evaluation.
A consultant has begun providing final design services.
Coordination to approve the schematic with TxDOT and the
Federal Highway Administration (FHWA) is underway.
• The NTTA has begun the process to procure a professional
services contract for Segment 5, which includes the
completion of the fourth- and fifth -level ramp connections
to the Dallas North Tollway (DNT), as well as new ramp
access to the Legacy Business Park area. Eight direct -
connect structures will be built, resulting in a fully directional
interchange. Construction of Segment 5 cannot begin until
TxDOT grants environmental approval, which is anticipated
later this year.
• The construction contract for Segment 3N was let in
mid - January 2008. Approval by the NTTA Board of Directors
is pending.
• Contracts are expected to be let for Segment 3S and for
signs, pavement markings, soundwalls and remaining traffic
control on Segments 1 and 2 on February 13, 2008.
• The NTTA expects to begin tolling operations for Segment 1
late in the second quarter of 2008.
• The NTTA also expects to begin operating and maintaining
SH 121 upon completion of the construction of Segments 1
and 2 in September 2008.
• Project limits: Business 121 (south of Denton Tap Road)
to Medical Center Drive (east of U.S. 75)
- Project length: Approximately 26 miles
• Project cost: Approximately $639 million (excluding
approximately $59 million for the expansion from six to
eight lanes)
- Anticipated completion dates:
— Segments 1 & 2: September 2008
— Segment 3: January 2010
— Segment 4: January 2011
— Segment 5: January 2012

signing, pavement markings, landscaping and installation of all -ETC and ITS systems.
Construction completion is scheduled for January 2011.
Segment Five (5) is currently a three -level interchange at the intersection of the Dallas North
Tollway (DNT) and SH 121. The existing three -level interchange will remain and be converted
by the NTTA to a five -level interchange with the addition of direct connect ramps. This segment
is planned for construction completion by January 2012.
PROJECT FUNDS
The current total estimated cost for the Project (Segments 1 — 5), for the three lane section
currently being designed, exclusive of interest and financing, but including a contingency
allocation, is $638,810,715, as shown in Table 3, page 11. The estimated cost was developed
based on the status of contracts awarded to date and is the best information available as of December
2007. The estimated Project cost reflects our professional judgment of the construction industry.
However, due to the nature of the construction industry we cannot, and will not, guarantee that the
actual Project cost will not vary from the estimated cost.

NORTH TEXAS TOLL WA Y UTHORITY SYSTEM
STA TE HIGHWA Y 121 TOLL PROJECT
DECEMBER 2007 PROGRESS REPORT
This report describes the location, engineering design features and construction cost estimates of
the State Highway 121 (SH 121) Toll Project (the "Proiect ") in Collin, Dallas and Denton
counties from Business SH 121 in Denton County to US Highway 75 (US 75) in Collin County,
a distance of approximately 26 miles. In addition, this report includes the engineering design
standards, typical sections and project plan and profile for the Proiect.
GENERAL
The Project extends northeasterly from Business SH 121 in Denton County to US 75 in Collin
County and continues to serve as a primary northeast - southwest traffic artery in the corridor area
between IH 35E and US 75. The corridor area served by SH 121 continues to experience
significant growth in commercial, retail and residential development. SH 121 is also a primary
arterial serving the Dallas -Ft. Worth (DFW) International Airport.
The purpose of the Project described in this report is to complete, expand, and improve the
roadway to meet the growing traffic demand in Collin, Dallas and Denton counties. The Texas
Department of Transportation (TxDOT) has completed and opened to traffic the frontage roads
for the entire length of the Project with exception of the frontage road reconstruction work
required to reconfigure the SH 121/ US 75 interchange in accordance with project requirements.
The Project is broken into five segments for purposes of managing and expediting the design and
construction (refer to Figure 1- Project map on page 2).

Progress Report #1 — December 2007
Segment One (1), the most southwesterly portion of the Project extends seven (7) miles from
Denton Tap Road/Denton Creek to FM 2281 (Old Denton Road). All bridge structures, ramps,
frontage roads, six (6) main lanes pavement and video tolling system (no toll tag readers) in this
Segment were constructed by TxDOT and opened to traffic in July 2006, as a six -lane video
tolled facility. The NTTA is responsible for constructing soundwalls, additional signing,
pavement markings, landscaping and installing all electronic tolling collection (all -ETC) (toll tag
readers and video) and Intelligent Transportation Systems (ITS). The NTTA's improvements are
scheduled for completion by September 2008.
Segment Two (2), the mid - western portion of the Project, extending nine (9) miles from FM
2281 to Hillcrest Road, is under construction by TxDOT and is scheduled for completion by the
end of August 2008. TxDOT is constructing all bridge structures, ramps and six (6) main lanes of
pavement. The NTTA is responsible for constructing additional signing, pavement markings,
landscaping and installing all -ETC and ITS systems. The NTTA's improvements are scheduled
for completion by September 2008.
Segment Three (3), the mid- eastern portion of the Project, extending seven (7) miles from
Hillcrest Road to Lake Forest Drive, is currently being designed by the NTTA. The existing
frontage roads and interchange at Custer Road were constructed and opened to traffic by
TxDOT. The NTTA is responsible for constructing a six mainlane tollway between the existing
frontage roads consisting of grading, drainage, structures, concrete pavement, retaining walls,
illumination, sign structures, bridge structures, signing, pavement markings, landscape and the
installation of all -ETC and an ITS systems. Construction completion is scheduled for January
2010.
Segment Four (4), the most easterly portion of the Project, extends three (3) miles from Lake
Forest Drive and terminates approximately one -half mile east of US 75 at Medical Center Drive,
a major arterial facility in the City of McKinney. The NTTA is responsible for constructing a
four -level interchange with direct connecting ramps at SH 121 and US 75 consisting of a six -lane
tollway on new location, reconstructing US 75 to an eight -lane facility, and realigning and
reconstructing the SH 121 frontage road network. Work consists of grading, drainage, structures,
SH 121 Tol/ Project Page 3 HNTB Corporation
Progress Report #1— December 2007
concrete pavement, retaining walls, illumination, sign structures, pavement markings, utility
relocation, landscape, and the installation of an all -ETC and ITS systems. Service roads will
provide access to US 75 from SH 121 until this interchange is completed. This segment is
planned for construction completion by January 2011.
Segment 5 is comprised of the interchange between SH 121 and the Dallas North Tollway
(DNT). The existing three -level interchange will remain and be converted by the NTTA to a
five -level interchange with direct connecting ramps. Work includes the completion of the fourth
and fifth level ramp connections to the DNT as well as new ramp access to the Legacy Park
Business area. A total of eight direct - connect structures will be constructed resulting in a fully
directional interchange. This segment is planned for constriction completion by January 2012.
The entire State Highway 121 Project is expected to include 3 mainlane toll gantries and 38 ramp
toll gantries, which will operate as all -ETC to maximize traffic flow. The gantry structures
accommodate the overhead placement of ETC equipment. The three mainlane gantries are
located near Denton Tap Road (Segment 1), Main Street (Segment 2) and east of Custer Road
(Segment 3). Each mainlane ETC gantry will provide for six initially and ultimately eight toll
collection lanes (three initially and ultimately four in each direction) that will be equipped with
both TollTag and TxTag collection capability. All toll collection lanes are dedicated, non -stop
express lanes to expedite the flow of traffic through the gantries and provide for ease of
maintenance. Refer to Figure 1 for tolled main lane gantry and ramp connection locations.
SH 121 Toll Project Page 4 HNTB Corporation
Progrevs Report #1— December 2007
The current estimated cost of the Project (Segments 1 -5), for the three lane section currently
being designed is $638,810,715. The total project cost including future capacity improvements is
$698,120,000. The required 350 to 400 - foot -wide Project right -of -way (ROW) was acquired by
TxDOT, Collin County, Dallas County, Denton County and the cities of Plano, Frisco, Allen and
McKinney. The estimated cost does not include funds for ROW acquisition services for minor
widening required at the interchanges at SH 121 /US 75 and SH 121 /DNT, where a total of seven
parcels (17.98 acres) are required prior to construction, which will be acquired by TxDOT at its
cost.
Construction contracts for structural steel fabrication and toll gantry construction required for all -
ETC operation of Segments 1 and 2 were competitively bid in November and December 2007,
respectively. A construction contract for construction of Segment 3N is scheduled to bid in
January 2008. A construction contract for signing, pavement marking, and soundwall
construction required in Segments 1 & 2 is scheduled to bid in February 2008. A construction
contract for construction of Segment 3S is currently under advertisement and will be bid in
February 2008. Quantities of the major construction items were developed from construction
plans and include grading, drainage, bridges, retaining walls, soundwalls, gantries, ETC and ITS
equipment, landscaping and related elements of construction. The estimated quantities and the
unit prices for similar construction in the Dallas area were used to estimate the total construction
cost. The unit prices are based on costs expected to be received through the competitive bidding
process in the first quarter of 2008. Quantities of the major construction items for Segments 4
and 5 were developed from conceptual schematic plans prepared by TxDOT. Construction plans
are scheduled to be completed for Segments 4 and 5 by late 2008.
Several factors, including unforeseen escalation of prices and wages, labor or material shortages
and changes in economic conditions can significantly affect (escalate or reduce) construction
costs. Appropriate contingencies are added to the cost of the Project to cover the unforeseen
escalations. The estimated Project cost reflects our professional judgment of the construction
industry; and it is our belief that the Project can be constructed within the limits described for the
estimated cost given herein. However, due to the nature of the construction industry we can-not,
and will not, guarantee that the actual Project cost will not vary from the estimated cost.

familiar with the highway construction industry. Neither the NTTA nor its consulting engineers
have control over the labor, materials or equipment costs; the contractors' methods of
determining bid prices; or competitive bidding, market, or negotiating conditions. The estimate
of construction costs given in progress reports will be monitored as work progresses on the
Project.

Progress Report #1— December 2007
DESIGN CONSIDERATIONS
The Project (existing and proposed sections) has been designed for a safe operating speed of 70
miles per hour. Wherever possible, desirable values for designs will be used to maximize safety.
The entrance and exit ramps will be designed to provide a smooth and safe transition between the
SH 121 main lanes and the service roads using 50 -mph design criteria.
The Project will initially provide six traffic lanes, three in each direction. The median width
varies from 28 feet to 52 feet throughout the length of the Project. A concrete median barrier will
be placed between opposing directions of traffic over the entire length of the Project to prevent
cross -over accidents. Should additional lane capacity be required in the future, the median will
accommodate one additional standard 12 -foot -wide lane in each direction, while maintaining a
center median barrier.
The NTTA has proposed to use its system -wide design guidelines and standards for Segments 3,
4 and 5, which include structural signing, bridges, retaining walls, ROW fencing, lighting, toll
gantry and landscape elements to promote visual consistency on all NTTA facilities. These
aesthetic elements are provided to enhance the NTTA customers' driving experience and
maximize safety for the motorists. The proposed Segments 3, 4 and 5 guidelines will match the
design guidelines used on the DNT extension at SH 121. Segments 1 and 2 will remain as built,
except for modifications to the toll gantries, bridge fencing, ROW fencing, landscaping, logos
and colors of the walls and bridge beams.
