I want to thank you for getting things organized as quickly as you did for us and for the follow up calls and site visits that allowed us to get this work done and meet our schedule dates for the road work.

The revised road structure number using the TX5 is 4.260 and a calculated traffic (ESALs) of 4,593,000.
