Work on the £78 million project to ease congestion at M6 Junction 10, between Wolverhampton and Walsall, is due to get under way in the new year.
The overhaul will see current bridges which run over the motorway replaced and doubled in size to help traffic run more smoothly at the notorious bottleneck.
Ahead of work starting, transport bosses have launched a traffic survey and are keen to hear from as many drivers who regularly use the route as possible.
The project is due to continue until the end of 2022. The existing bridges will remain open to traffic while the replacements are built but disruption is still predicted as the scheme progresses.
Transport for West Midlands (TfWM) says it plans to use the information gained from the survey to help advise motorists how and when to travel, provide alternative routes and encourage car sharing and other sustainable transport methods in an effort to prevent major delays.
Traffic regularly backs up on the Black Country Route and Wolverhampton Road, either side of the junction, at peak times and transport officials are confident the project will help solve some of the issues faced by drivers.
Walsall Council deputy leader Adrian Andrew said: "Congestion is a headache for drivers and residents alike. This survey will help planners make the right decisions for all of us and I’d encourage Walsall residents to take part."
Anne Shaw, director of network resilience at TfWM, said: "Useful and reliable information during roadworks is essential to help people move around the region.
"We’re really keen to speak to people who travel through or along the M6 to help them plan ahead and keep moving while the work takes place. We are pleased to be able to support Walsall Council as they prepare for this transformational project."
