On January 30, 2026, a Washtenaw County Road Commission (WCRC) contractor began working to prepare the intersection of Parker Rd at Shield Rd in Lima and Scio Townships for the installation of a three-way traffic signal.
During the week of February 2, 2026, the contractor completed the installation of two traffic signal pole foundations.
Next steps
- Complete the pole foundation installations
- Install the overhead traffic signal equipment
The contractor will finish the remaining pole foundation work and then will temporarily cease operations on site for several weeks. This pause is necessary to allow the concrete foundations to fully cure and to wait for the arrival of the remaining equipment. Once the curing process is complete and the equipment has been delivered, the contractor will return to continue the work.
WCRC will keep residents informed as the intersection improvements progress.

ISSUE DATE: 01/06/2025
The Washtenaw County Road Commission (WCRC) is pleased to announce an upcoming project at the intersection of Parker Road and Shield Road, located on the border of Lima and Scio Townships.
This project, scheduled for the 2026 construction season, was prompted by WCRC’s ongoing monitoring of traffic congestion and safety. To address these concerns, WCRC successfully secured a $280,000 Federal Carbon Reduction Program (CRP) grant to fund the installation of a new traffic signal. This signal is designed to alleviate congestion during peak travel hours and reduce carbon dioxide emissions by improving traffic flow and reducing vehicle idling.
Construction is expected to take place in the spring of 2026. To minimize the impact on commuters, the intersection will remain open during work, though motorists should anticipate lane restrictions and flagging operations.

WCRC will post project updates online at wcroads.org and on its Facebook and Twitter pages.
