Q: 4100 South has been under construction before, why is reconstruction happening again?

A: This reconstruction is happening to add consistent improvements throughout the corridor and install a new water line in coordination with Granger-Hunter Improvement District. We are hopeful that this project will be a long-term solution on 4100 South to avoid numerous smaller construction projects on the corridor in the future.

Q: What can I expect during construction?

A: ​​During construction, 4100 South will be brought down to one lane in each direction. Because of the reduced lanes, Drivers should expect heavy traffic delays and use an alternate route if possible. In addition:

​-Daytime work activities

-Noise, dust and vibration

-Lane restrictions and changing travel patterns

-Trucks and equipment entering/exiting the work zone
