Following the end of the public comment period on Jan. 22, the state is now moving forward with plans to install dedicated bike lanes on the Craigie Bridge.
Current conditions on the bridge, which carries traffic on the McGrath O’Brien Highway (Route 28) between Land Boulevard in Cambridge and Leverett Circle in Boston, include six travel lanes with no dedicated bike lanes leaving bicyclists to use travel lanes or the sidewalks and no defined turn lane into the Museum of Science, according to The Massachusetts Department of Transportation (MassDOT).
MassDOT and the Department of Conservation and Recreation (DCR) unveiled two bike-lane options, as well as planned safety improvements for the bridge, on Dec. 18 at the MIT Stratton Student Center in Cambridge.
New safety measures, which are slated for completion by this spring, include changing speed-limit signs to 25 mph; installing “speed feedback” radar signs; conducting road-safety audit; installing pavement-marking change; and installing flex posts if possible, according to MassDOT.
The design team presented two options for creating bike lanes, both of which would eliminate one traffic lane.
The first option, which was developed in 2008, would create continuous on-road bike lanes and maintain the existing sidewalks while providing two travel lanes in each direction and adding a left turn into the Museum of Science.
The alternative is just like the first option, except that it would create three travel lanes into Leverett Circle and restrict left turns into the Museum of Science.
The final design is expected to be presented in the winter of 2019, wrote MassDOT spokesman Maxwell Huber.
“O’Brien Highway is a key bike route between Cambridge and Boston,” according to a statement from the Boston Cyclists Union. “It’s also eight lanes wide in parts, with a high volume of truck traffic and speeding vehicles. Protected bike lanes are absolutely necessary to minimize conflicts on this road.”
The bridge was the site of a fatality on Nov. 9 of last year when 24-year-old Boston University Meng Jin,24, was struck and killed by a dump truck while biking there.
Stacy Thompson, executive director of the Cambridge nonprofit Livable Street Alliance, is pleased that the state is proceeding with the project, albeit more slowly than was originally anticipated.
“Citizens have been advocating for bike lanes since the late ‘90s…and we’ve been asking for these changes for more than a decade,” Thompson said. “There was a commitment when Longfellow Bridge rehabilitation project was complete that they would install the bike lanes, but there were various delays with that bridge and now that it is complete, we still don’t have the bike lanes [on the Craigie].”
While Thompson said she sees no merit in debating which alternative is preferable, especially since they were developed, at least in the case of the first option, more than a decade ago, she emphasizes that “the devil is in the details,” such as connectivity to the Charles River and whether or not buses can make a left turn into the Museum of Science.
“Having strong biking infrastructure is an absolute must, but they still have work to do so that the bridge can move the most people, which includes improving walking and biking infrastructure,” Thompson said.
State Rep. Jay Livingstone also said he was pleased that the project is moving forward while underscoring the bridge’s potentially hazardous conditions. “I think current situation is unsafe for pedestrians and bicyclist, and I think separated bike lanes should be installed with minimal disruption to current traffic,” Livingstone said. “I’m pleased that MassDOT is doing the public process with all stakeholders involved so that everyone has a say.”
