Motorists can expect single lane traffic through the tunnels Monday through Friday at noon controlled by a signal system starting on Sept. 8. Portable barrier will be in place along the center line through the project duration. Work will take place first at Silver Cliff Tunnel then move to the Lafayette Bluff tunnel. There will be no traffic impacts on the weekends, and closures will take place at one tunnel at a time. Work is expected to last through late October.
About this project
Summary of work
Project location map
During the Fall of 2019, crews performed an inspection of existing tunnel lighting supports over the centerline in the Silver Creek Cliff and Lafayette Bluff tunnels. The inspection was needed to verify the structural capacity of the existing lighting support system in preparation for the design phase of the lighting upgrade project.
A new LED lighting system will be designed to upgrade the luminaires and lighting control system in each tunnel.
