The 1.2 miles in Framingham were paved in 2015. Construction of a 12-foot-wide multi-use path along the remaining 2.4 miles in Natick finished in September 2021. It includes a new bridge across Route 30, as well as replacement of the CSX bridge over Route 9. The Wonder Bread Spur was built at the same time.
