CURRENT DESIGN RECOMMENDATIONS
The Town of Watertown is in the process of refining the design of the Mount Auburn Street corridor. The project team is analyzing segments of the corridor based on their different transportation needs, varying land use and unique character.
The project team is continuing to analyze alternatives for each segment of the corridor based on public comments and coordination with the City of Cambridge and the MBTA. At the November 20, 2017 presentation to the Watertown Town Council Public Works Committee, the project team presented the below recommendations for the corridor.
West of Common Street
Traffic volumes require maintaining four lanes of travel (two lanes in each direction). There are no proposed changes to the existing roadway configuration at this time.
Common Street to Dexter Avenue
Traffic volumes allow for the road diet, or one travel lane in each direction. There is space available for left turn pockets at a majority of the intersecting side streets.
On the north side of Mount Auburn Street (to Watertown Sq.), a buffered bike lane along the curb (with a 3-foot painted buffer) is proposed. Flexible posts can be considered in the future.
On the south side of Mount Auburn Street (to Cambridge), a buffered bike lane between the travel lane and the parking lane (with a 2-foot painted buffer on each side) is proposed.
Coolidge Square (Dexter Avenue to Arlington Street)
The design of this segment is in progress. An open house will be held in January 2018 to discuss the unique features and challenges in this corridor, including additional parking demands, limited business district designation, a need for loading/delivery areas, and pedestrian activity.
Arlington Street to Cambridge city line
A separated bike lane in each direction is not feasible based on the project team's analysis. The project team is investigating a combination of separated/buffered options in this segment.
At signalized intersections, bike boxes, striping and additional signage will help increase drivers' visibility of bicyclists. Similarly, pavement markings will be installed to call attention to bicyclists in the road at unsignalized intersections.
The plans will continue to change as the design advances. Selected, preliminary intersection plans can be found in the presentation from the December 8, 2016 public meeting. Additional intersection plans can be found in the December 2016 Roll Plan. However, these plans do not reflect the recommendations outlined above and will be updated as the 25% Design process continues. Additional conceptual design plans and supporting materials can be found on the Documents page.
