Street Project: E. Deinhard Lane, SH55 to Samson Trail


  Update:  September 26, 2023: 

Attention all drivers and commuters: We want to ensure you are well informed about the key details and changes that will be in effect.

Access to the McCall Marketplace and US Post Office via Deinhard Lane (near Commerce Street) is closed this week and expected to open again in the next week.   

Deinhard Lane is closed to thru-traffic, but access to McCall Marketplace and the US Post Office is provided at the west entrance off 3rd St.  All thru-traffic on Deinhard is being detoured around the construction site via Jacob Street.

Periodic Flagging for traffic control until the end of October. 

At the Marketplace's west entrance, traffic control measures will be in place. Drivers exiting the Marketplace’s west entrance will be directed to make right turns only. This strategic approach aims to alleviate congestion, minimize wait times, and facilitate efficient traffic flow out of the shopping center.As this construction phase progresses, we extend our sincere gratitude for your patience and cooperation. Your understanding is crucial as we work diligently to enhance the roadway infrastructure for the benefit of the entire community. Stay tuned for further updates and adjustments as we continue to make strides in this project. 

This may cause traffic disruptions for commuters and residents in the area. 

During the closure, motorists are advised to use alternative routes and follow the posted detour signs. Pedestrians and cyclists are also urged to exercise caution when navigating the affected areas and note the pathway is open.  

Local businesses and residents are encouraged to plan ahead and make necessary arrangements to minimize any inconvenience caused by the road closure.
