Ret Denton Tap Road Bridge
Concrete Strength Evaluation
Dear Sir:
We request your approval to obtain three concrete core samples from the
deck of the existing Denton Tap Road Bridge over Denton Creek. This work is
required to determine the strength of the existing bridge in anticipation of
the proposed widening of the bridge by the Denton County Road Utility District
No. 1. The three core samples will be four inches in diameter by three inches
deep and will be located along the bridge deck centerltne. Following the
completion of the coring operations, holes will be patched and repaired with
high strength epoxy grout.
Your approval will be most helpful in assisting us with the design of the
proposed bridge improvements. Should you have any further questions please
feel free to contact us.
