Re:
Denton Tap Road Improvements from Belt Line Road to Sandy
Lake Road from Sandy Lake Road to Denton Creek, Coppell,
Texas.
Dear Mr. Snyder:
We are forwarding your letter of August 25, 1988, concerning the
speed limit on Denton Tap Road to the City Engineer, Mr. Russell
Doyle for his consideration. It has been our experience on past
projects in Coppell that City Council action is unnecessary for
establishing temporary, lower speed limits in construction areas.
We would like to point out that L.H. Lacy Company, as the
Contractor, has a responsibility under the Contract to post the
appropriate speed limits within the limits of construction, and
the traveling public has the responsibility to observe all
warning signs in construction areas as prescribed under the laws
of the State of Texas. Please refer to the Contract, Section
00650 Special Conditions Paragraph 1.4, B. on page 4; Paragraph
1.25, 1. on page 15; Paragraph 1.25, 12. on page 17. For your
convenience we have attached copies of these pages highlighting
the applicable sections.
Safety is of the utmost importance, and we appreciate your
awareness and commitment to safety on this project. Please call
me if you have further questions or concerns regarding this item.
