In January of 2016, a preliminary Functional Design Report (FDR) was submitted to MassDOT and the Boston Region Metropolitan Planning Organization, prior to beginning work on the 25% design plans for the Mount Auburn Street Corridor Project. This was necessary to gain early acceptance of the concept of a road diet along Mount Auburn Street and to obtain funding for the project.
The FDR is an evaluation of the current Mount Auburn Street corridor from Patten Street, just east of Summer Street to the Cambridge City limits. It also includes a section of Arlington Street, beginning north of the intersection with Mount Auburn Street and continuing south to Grove Street terminating at Merrifield Avenue. It assesses existing conditions, identifies operational and safety deficiencies, and recommends an improvement strategy to address any deficiencies identified.
During development of the concept plans, it was evident a revised FDR would be necessary to capture changes in the design as a result of our robust public participation process, recent changes in traffic volume projections, and incorporation of bus transit priority. This FDR, prepared in June of 2021, replaces the previous version with updated crash data, revised traffic volumes, traffic operations analyses, concept plans for the corridor, and ultimately supports the 25% design plans.
