Bowker Overpass

Bowker Overpass is a steel bridge in Boston that spans across Interstate 90 and connects Boylston Street with Storrow Drive. The structure runs parallel to the Muddy River and forms a key traffic junction between Back Bay and the eastern streets of the city.

This structure was completed in 1965 by the Massachusetts Department of Transportation to improve traffic flow between major urban areas. Its construction was part of Boston's post-war expansion of transportation infrastructure.

The bridge crosses over the Muddy River and shapes how people experience the boundary between the park system and the city. Those on foot or bicycle notice it as a defining feature when moving through this area.

The overpass is designed for drivers between Back Bay and Downtown, offering direct access to Interstate 90 and eastern roadways. Those exploring this area on foot or by bicycle should expect heavy traffic and stick to designated paths.

Major rehabilitation projects will fundamentally reshape the structure and reconfigure the eastbound section of Storrow Drive. These planned works show how this critical traffic route continues to adapt to modern needs.
