Route 20 Intersection Study

Vanasse Hangen Brustlin, Inc. (VHB) was retained by the Town to conduct a transportation study of three intersections and the surrounding areas to identify potential improvement options. 

The full report found below presents the findings and recommendations of the study, which assessed the following intersections:

  • Boston Post Road at School Street and Church Street (all approaches)
  • Route 20 (Boston Bypass Road) at Boston Post Road and Wellesley Street
  • Route 20 (Boston Bypass Road) at School Street

The study was presented in a public forum hosted by the Select Board and the Traffic and Sidewalk Committee in December 2014. Public feedback regarding the intersection at Boston Post Road/Wellesley Street was given to VHB and used to further develop traffic relief at this intersection. The design for this intersection is currently still under development.

Rt. 20 @ School Street

The Traffic & Sidewalk Committee received notice from MassDOT regarding its plan for roadway resurfacing work along Route 20 in 2017. Two concepts were reviewed by the Traffic & Sidewalk Committee and the Select Board before work began. 

The state widened 120 square feet of roadway and re-striped a turn lane, which lengthened the eastbound right turn lane from 70 feet to 140 feet.  

Church St./Boston Post Road

The engineering study and additional information regarding this intersection improvement were given to the Town Center Planning Committee and its traffic engineers to incorporate in the Town Center Improvement Project. 

Construction funds were approved by the 2019 March Special Town Meeting and construction is underway.

Study Recommendations - Project Background

The recommendations above were developed through several working meetings with the town’s Traffic and Sidewalk Committee. The formation of these recommendations considered limiting impacts to property, highlighting access for non-motorized transportation, improving traffic congestion, and improving traffic flow through town. 

As discussed in the report, improvements involving Route 20 would require the review and approval of MassDOT, regardless of whether the improvement is being funded by the town or the state through the TIP process. MassDOT has reviewed this report and provided suggested recommendations. These are detailed in Chapter 4 of the report.
