Diehl Road Added Turn Lanes

Project Overview:
In December 2014, the City was awarded federal Surface Transportation Program (STP) funding that will cover 70% of construction costs to make turn lane improvements on Diehl Road.   The Phase I engineering study includes the creation of a new left-turn lane with 200-feet of storage into a private development to relieve congestion of westbound through traffic on Diehl Road.  As part of this project, an additional 100-feet of storage will be added to the dual left-turn lanes from eastbound Diehl Road to northbound Winfield Road.  The awarded STP funding is dependent on demonstrating that this project would have public benefit to traffic on Diehl Road. 

Consultant Selection: James J. Benes was selected as the most capable project team for Phase II Final Engineering and Phase III Construction Engineering.

Schedule:  The April 26, 2019 letting low bidder was Alliance Contractors, Inc. 

Next Steps: Construction to be completed by the end of September, 2019.
