About the Project
The project reconfigures the Thayer Drive/Duportail Street intersection with a single-lane roundabout. Duportail Street will extend from Thayer Drive to Wellhouse Loop to provide two travel lanes, a two-way center left turn lane, bike lanes and sidewalk on both sides of the street. A new signal will also be constructed at the intersection of Duportail Street and Wellsian Way.
