The Michigan Department of Transportation announced on April 6 that a two-year project to install soundwalls along a section of northbound Interstate 75 in Troy will begin Friday, April 10, weather permitting. The work covers a 2.7-mile stretch from Wattles Road to Coolidge Highway and includes the installation of two soundwalls, as well as safety improvements.
This project is intended to reduce noise for nearby neighborhoods and improve roadway safety. The $14.5 million investment is expected to directly and indirectly support 123 jobs during its duration.
According to the department, contracting crews will start by placing temporary barriers and shifting traffic along northbound I-75 from Wattles Road to Coolidge Highway. To protect workers and drivers during this phase, the right lane will be closed over the entire length of the work zone. Lane closures are scheduled for off-peak hours on weekdays and at all times on weekends until new traffic patterns are established.
Throughout construction, three travel lanes will remain open through the work area during peak periods. The high-occupancy vehicle lane requirements between Big Beaver Road and Coolidge Highway will be suspended while work is underway. Access from northbound I-75 to Crooks Road/Corporate Drive interchange will continue without interruption.
In addition to installing soundwalls from Wattles Road to Long Lake Road and from Crooks Road to Coolidge Highway, crews will add guardrails, make shoulder improvements, and realign drainage systems as part of broader infrastructure protection efforts.
