ST8505-CS 850703 ITEM #13
BELT LINE/DENTON TAP/SOUTHWESTERN INTERSECTION
Two alternatives have been investigated for the Belt Line/
Denton Tap/Southwestern intersection and are shown on the
attached drawings. Both alternatives will require additional
right-of-way.
Alternative I illustrates the intersection as skewed at
13 degrees and requires several median strips to properly
direct traffic. The median strips and unfamil~.ar right and
left turn lanes would be confusing to motorists approaching
the intersection. Traffic flow with this alignment would, not
operate at optimum safety and efficiency. This alternative
will require 0.294 acres of additional right-of-way along
Southwestern from the Southwestern Town Lot Corporation and
0.066 acres of additional right-of-way along Belt Line Road
(East) from James W. Whitehead.
The other alternative, which we consider as our base
proposal, provides a standard 90 degree intersection for
these four roads. This alignment provides a safer and less
confusing intersection than Alternative I. Belt Line and
Denton Tap would be designed as six-lane divided
thoroughfares and Southwestern would be improved to a
four-lane street with an extra wide median at the
intersection only. The wide median provides the option of a
future six-lane divided roadway west or a landscape focal
point for the City in the future. The existing Southwestern
Boulevard would remain in operation but would be converted to
a one-way (westbound) street from Denton Tap to Bullock
Street. This alternative will require 1.102 acres of
additional right-of-way along Southwestern from the
Southwestern Town Lot Corporation only.
On January 21, 1986, we met with representatives for the
owner on the southwest corner of the intersection, Santa Fe
Pacific Realty, and they expressed at that time a desire to
have the intersection constructed as a 90 degree
intersection.
It is our recommendation that you adopt the base proposal
intersection design and include it as part of the Master
Thoroughfare Plan. We can work toward obtaining the
right-of-way and constructing the whole intersection at this
time or, at a future time whenever the property is platted,
the City could require dedication and require the developer
to construct the roadway.
Action Required: Recommend adoption of the Base Proposal
Design for inclusion in the City of Coppell Master
Thoroughfare Plan.
