Western Avenue & SEC Enabling Roadway Projects

As part of the roadway enabling work for Harvard's new Science and Engineering Complex (SEC), a section of Western Ave needed to be realigned to accommodate the installation a new utility tunnel to service the complex, running across Western Ave from the former Charlesview site to the new SEC project site. 

The first phase of the roadway realignment was successfully completed in May 2017 and extends from 130 to 140 Western Ave. The final phase was successfully completed in late February/early March 2020 when the realignment was reversed, returning Western Ave to its original layout. 

The other roadways around the SEC and 114 Western Ave, including Western Ave, Academic Way, Science Drive, Rotterdam Street and Stadium Road, called for new sequencing, paving, and some underground utility work to facilitate the opening of both the SEC, 114 Western Ave, and the new Enterprise Research Campus. These roadways continued to open in phases throughout November/early-December 2020.
