Monsignor O'Brien Highway Reconstruction - Phase 2A (Lechmere Canal Outfall)
In order to develop Cambridge Crossing, DivcoWest was required to make improvements to Monsignor O’Brien Highway from Third Street to Museum Way. These improvements have included subsurface and surface infrastructure upgrades. This section of Monsignor O’Brien Highway is being transformed from a highway into a tree lined boulevard with bicycle lanes/cycle tracks, new sidewalks and significantly improved pedestrian crossings. Due to the construction associated with the MBTA’s Green Line Extension (GLX) Project, these improvements have been phased over several years.
