The MetroWest Regional Collaborative and Metropolitan Area Planning Council will hold their final public meeting on plans for improving Route 9 in four communities at the Morse Institute Library from 7 to 9 p.m. May 20. The meeting will focus on the effect of the proposed changes for the stretch of Route 9 in Southborough, Framingham, Natick, and Wellesley, including the potential addition of compact mixed-use developments that are more accommodating to pedestrians and bicyclists. At the forum, planning officials will also discuss traffic issues relating to “smart growth” areas, design guidelines and recommendations, and implementation strategies and phasing. The library, at 13 East Central St., is accessible to those with disabilities. Individuals needing special accommodations to participate in the meeting should contact Bruce Leish at 508-881-2924 or firstname.lastname@example.org.
