Connect Historic Boston

We’re working to connect historic sites in downtown Boston. We want you to be able to safely bike, walk, and drive to these locations.

We are into the last stretch for the work from Staniford Street to Atlantic Avenue. That work will be completed this construction season. Work on the Blackstone Block and Constitution Road has started.

The initiative between the National Park Service and Public Works is funded through a federal Transportation Investment Generating Economic Recovery (TIGER) grant. We’re also working in coordination with:

We’ve already started construction on the project, and we are scheduled to finish all work by mid 2018. The general contractor for the first phase of the project is P.

That work has started at the Blackstone Block and Constitution Road. All work under this contract is scheduled to be complete by July 1, 2018.

More details about our projects

Sitting next to the Fanueil Hall Marketplace, the Blackstone Block represents the core of Boston’s historic market district. The roads and alleys connecting to the Blackstone Block are the City’s most intact colonial-era street network. We’re reconstructing the area to give visitors a better experience as they explore this unique urban landscape, Creek Square, and Haymarket.

Mobilization began the week of May 29, 2017 and utility and sidewalk work has begun.

The plan is to create a family-friendly, low-stress bicycle trail that makes a full circuit of downtown Boston. During Phase One of the project, we’ll  creates a grade-separated, protected cycle track along Staniford Street, Causeway Street, Commercial Street, and Atlantic Avenue. We’ll also complete a full reconstruction of Causeway Street to aid pedestrian safety and accessibility.

Work started in April 2015 on Staniford Street and continued through November 2015 along Causeway Street to the intersection of Portland St. as well as work on Commercial St. In 2016 major portions of work were completed on Causeway St. between Portland St. and North Washington St.  Final roadway paving was installed on Staniford St., the project's portion of Lomasney Way and Causeway St. to Portland St.  Final paving was also installed between Prince St. to Battery St. A partial opening of the cycle track was allowed in the finished portion of the work.

Though a small roadway, Joy Street is the only direct connection across Beacon Hill from Boston Common to Cambridge Street. This project will rebuild Joy Street as a shared roadway without curbs — in Dutch, a woonerf. The roadway will slow vehicular traffic and improve the environment for pedestrians.

We’ll also focus on easing walking access to the Boston African-American National Historic Site, which hosts a half million visitors each year.  This work will be near end of  late 2017.
