Re: Coppell Road Reconstruction
SH 121 to Sandy Lake Road
Dear Mr. Young:
TELEPHONE (214) 358 -6581
Enclosed for your review and approval is a copy of our revised traffic control plan for phase 2 of
the project. This phase includes construction of a two lane bypass detour, in accordance with the
City of Coppell's directive regarding traffic control during construction of the box culvert, and
constriction of the box culvert.
EBCC has been successful negotiating an agreement with the adjacent property owner to allow
EBCC to "slide" the detour to the west. By utilizing the slope easement and an additional
portion of his property, EBCC can provide enough standoff from the traveling public to ensure
worker safety during construction of the box culvert and allow for single stage construction of
the box culvert. The enclosed traffic control plan reflects the alignment of the. detour that will
allow single stage construction of the box culvert.
Advance signage for the bypass detour will be installed in accordance with figure 6 -2 of the
Texas Manual of Uniform Traffic Control Devices. EBCC requests City of Coppell approval to
post the construction zone speed at 20 MPH. In addition to the vertical panels utilized to
channelize traffic to the detour, EBCC will utilize paint or buttons to delineate lanes on the
detour and transition areas.
If you have any questions regarding this information, don't hesitate to contact our office.
incerely,
d e 1 C nstru i n Company
