Woodhaven’s Allen Road Railroad Bridge Project: What’s Happening and When Will It Be Finished?

Updated November 9, 2026

If you’ve spent much time driving through Woodhaven, chances are you’ve encountered one of the area’s most frustrating traffic problems: a train blocking Allen Road.

Sometimes the wait is a few minutes. Other times, it can disrupt an entire commute.

That’s why the Allen Road Grade Separation Project is such a significant undertaking for Woodhaven and the surrounding Downriver communities.

But what exactly is being built, why is Allen Road closed, and when will drivers finally be able to travel through without waiting for trains?

What Is the Allen Road Grade Separation Project?

The project will lower Allen Road beneath the existing railroad crossing near Van Horn Road and construct a new railroad bridge overhead.

Once completed, trains will travel across the bridge while vehicles pass underneath, eliminating the need for drivers on Allen Road to stop for passing trains at that location.

The work also involves relocating utilities, improving drainage infrastructure, and installing a pump station to serve the lowered roadway.

Wayne County is leading the project in cooperation with the City of Woodhaven and Canadian National Railway.

Why Is This Project Necessary?

The Allen Road railroad crossing has been a longstanding transportation problem.

According to Wayne County, more than 30,000 vehicles use the crossing daily, including approximately 2,140 commercial trucks.

Train-related stoppages average more than nine minutes, and some have lasted 45 minutes or longer.

Those delays affect more than commuters. They can interfere with school transportation, deliveries, local business access, and emergency response.

The goal is to make travel through this important Downriver corridor more predictable and reliable.

Why Is Allen Road Closed?

Construction requires extensive work beneath and around the existing railroad crossing.

The project includes:

Lowering the roadway beneath the railroad tracks.
Building a bridge to carry trains over Allen Road.
Relocating underground and overhead utilities.
Installing drainage and pumping infrastructure.
Maintaining railroad operations during construction.

The closure began March 23, 2026, between Van Horn Road and West Road.

During construction, motorists must use alternate routes. Wayne County provides an official project map and detour information to help drivers plan their trips.

Because construction conditions can change, drivers should check the county’s latest updates rather than rely on an older detour map.

What’s the Latest Update as of November 2026?

The project remains in its scheduled 2026–2028 construction period.

Woodhaven’s November 3, 2026, City Council agenda included a resolution concerning an agreement for additional professional services associated with the grade separation project.

That agenda item demonstrates continued municipal involvement, but the agenda alone does not establish whether the agreement was approved or whether the construction schedule has changed.

Wayne County’s published project information continues to provide the most useful official overview of the work and its anticipated timeline.

When Will the Allen Road Project Be Finished?

According to Wayne County’s published schedule, Allen Road is expected to reopen to traffic before fall 2028.

The broader project is anticipated to reach completion around the end of 2028.

Those are projected dates, not guaranteed deadlines. Major infrastructure projects can be affected by weather, utility relocation, engineering conditions, and construction schedules.

For the most accurate information, residents should follow Wayne County’s official project updates.

What Does This Mean for Woodhaven Residents and Homebuyers?

In the short term, construction means detours and changes to familiar travel routes.

For people considering buying a home in Woodhaven or neighboring communities, it’s worth understanding how the temporary closure may affect a commute, school transportation, or access to frequently visited businesses.

Longer term, the project is intended to eliminate train-related delays at this crossing and improve the reliability of Allen Road.

That doesn’t automatically mean nearby home values will rise. Real estate values depend on numerous factors, including property condition, location, available inventory, and buyer demand.

But transportation improvements are certainly part of understanding how a community is evolving.

Frequently Asked Questions

Is Allen Road completely closed?

The construction closure affects Allen Road between Van Horn Road and West Road. Other portions of Allen Road remain accessible, subject to current traffic restrictions.

Will trains continue running during construction?

Yes. The project includes a temporary railroad alignment, sometimes called a shoofly track, to maintain rail operations while the bridge is built.

Will the new bridge eliminate all railroad delays in Woodhaven?

No. It is designed to eliminate train-related stoppages at this particular Allen Road crossing. Other railroad crossings in the area will remain.

The Bottom Line

The Allen Road Grade Separation Project is a major investment in Woodhaven’s transportation infrastructure.

While the construction period requires patience, the finished project is intended to solve a problem Downriver drivers have dealt with for decades.

For homeowners and buyers, staying informed about projects like this is part of understanding the communities where we live and work.
