The state’s Department of Conservation and Recreation (DCR) will present current design plans for a Morrissey Boulevard reconstruction project on Tuesday, Sept. 27. The meeting is scheduled for 6:30 p.m. to 8:30 p.m. at the Leahy Holloran Community Center (1 Worrell St.) in Dorchester.

The designs set to be presented for the likely $40 million project are “conceptual,” according to a meeting notice.

“The focus of this meeting will be concepts for the reconfiguration of roadway lanes, intersections, crosswalks, and adjoining sidewalks and paths used by pedestrians and bicycles,” according to a DCR meeting notice. Public comments on the proposals and the meeting will be open until Oct. 18.

Community members have long expressed concerns about traffic and safety on the stretch of road running between Kosciuszko Circle to Neponset Circle. High-profile building developments along the Morrissey corridor — including an expansion of the UMass Boston campus— have increased congestion, and coastal flooding often leaves the roadway partially or completely closed.

Studies included in a DCR presentation on the project identified the heaviest traffic congestion sites as Freeport Street and UMass Boston at Mt. Vernon Street. The presentation identified the middle segment of the road -- Bianculli Boulevard to Freeport Street -- as the most vulnerable to flooding and the highest priority if funding limitations require a phased construction schedule.

DCR officials started the design phase of the long-awaited reconstruction after a public meeting in March. A schedule distributed at the time presumed a public presentation of designs in May, which would involve a design mockup for the entire stretch of the oft-flooded roadway.

But a late start to the public presentations pushes the overall timeline further along. As laid out in March, officials expected to present 25 percent, 50 percent, and 75 percent designs throughout the summer, with a final design presentation in December 2016.

Attendees at the last public meeting in March identified priorities for beautification and access along the parkway, with most asserting that they would not brave the corridor as pedestrians or bicyclists. Creatively improving drainage and implementing safeguards such as elevated roadways were offered as potential measures at the meeting.

The presentation will be available online after the meeting, as are materials from the earlier community gathering.
