Re: WalkBoston comments on Craigie Dam/Bridge Design Alternatives

We are relieved that MassDOT and DCR are committed to acting to improve the safety of people walking and biking on this critical roadway segment.

We have reviewed the options that were presented to the community on December 18th and have several comments that are detailed below. However, we do not think that the relatively modest improvements that are planned for Spring 2019 are adequate to providing truly safe walking and biking conditions, and we urge MassDOT and DCR to develop more significant plans for safety for the Charles River bridges.

One approach that WalkBoston would like to see explored is the adoption of a pilot 20 MPH speed limit on all the Charles River Bridges from Harvard Square to the Craigie Dam/Bridge that would test an automated speed enforcement protocol. Over the last month we have attended meetings regarding safety and operations for the BU Bridge, the Longfellow Bridge and the Craigie Dam/Bridge. In each case, the completely fixed and limited right-of-way does not allow for the provision of protected bike accommodations within the roadway right-of-way without reducing the number of vehicle lanes. WalkBoston was distressed to hear suggestions by community members at one of these meetings to dedicate one of the sidewalks to bicycles rather than pedestrians in order to free up roadway space for vehicles (a suggestion that we were pleased was simply given, but then not taken up or discussed by any of the state or municipal staff).

MassDOT has already expressed its interest in adding automated enforcement to the state’s safety tools and we urge MassDOT to vigorously support a pilot program for the bridges. Setting and then enforcing a 20 MPH speed limit on all the bridges would significantly increase the safety of bicyclists using on-street bicycle lanes while at the same time allowing the number of vehicle lanes to remain as they are today.

Comments on Design Options A and B

Craigie Dam/Storrow Drive Intersection

Take the following steps to minimize conflicts between people walking, biking and driving:

  • For turns from Craigie into Storrow Drive put in place (and enforce) a permanent No Right on Red regulation and include the permanently illuminated NRTOR sign
  • Set the vehicle for Craigie Dam traffic approaching Leverett Circle stop line back from the intersection (with Don’t Block the Box markings and enforcement) to allow bikes to queue in a bike box ahead of traffic
  • Provide marked bike lanes from Craigie to Martha Way through Leverett Circle
  • Tighten the turning radius of the corner from Craigie onto Storrow Drive and provide a bike ramp to the Paul Dudley White Path at the corner rather than having bikes get on the sidewalk before reaching the intersection. The very tight sidewalk space should be reserved for pedestrians.

Museum of Science Driveway and Museum Way/Craigie Intersection

  • Add crosswalk striping across the Museum of Science driveway.
  • Narrow the driveway to the greatest extent possible given the truck and bus movements needed for Museum of Science operations.
  • Consider signalizing the driveway entrance to the Museum of Science in coordination with the Museum Way signal.
  • Eliminate the conflicting left turn arrow across the WALK signal at the Museum Way crosswalk across Craigie.
  • Improve the street lighting of the crosswalk across Craigie at Museum Way

Craigie/Land Boulevard/Gilmore Bridge Intersection

Configure the signal timing at the Land Blvd/Craigie/Gilmore Bridge intersection to allow safe pedestrian and bike movements. A detailed description is provided below of the maneuver needed to ride a bike safely through the intersection under current conditions. This is in urgent need of improvement.

  • “At the intersection with Edwin H Land Blvd/ Gilmore Bridge, to feel safe as a bicyclist I will often violate traffic signals. The problem is that, whether traveling either inbound or outbound, if you wait for the light to change, traffic builds up next to you. When the light turns green, you are forced into the middle of a pack of fast-moving traffic, with cars and trucks rapidly accelerating and changing lanes.

    The situation is particularly dangerous when traveling outbound and making a left on Cambridge Street (a route most bicyclists take, as Route 28 gets faster and more dangerous beyond the Cambridge St. intersection). As a bicyclist, if you leave the Gilmore intersection with vehicle traffic, you then have to work your way across 2 lanes of fast-moving traffic to get into your left turn, and then must hold your ground in the middle of four lanes of outbound traffic in order to end up on the right-hand side of the two lane Cambridge St. turnoff. You can also hug the left-hand side of the road by the median strip, but traveling on the left side of the road can be dangerous too.

    I have found navigating the Science Bridge is actually safer when breaking the traffic signals. For example, when traveling outbound, if I hit the red light at the Gilmore intersection, there is a break in the signal when I usually run the red light on my bike. The break occurs between the green light for vehicles coming from Charlestown towards Cambridge, and the following green light for traffic moving inbound on 28. Taking the light this way has dangers too – at least one or two vehicles coming from Charlestown almost always speed through their red light (committing their own traffic violation), and you need to be absolutely sure those vehicles have stopped. Nevertheless, this method still allows me to make my way over to the Cambridge St turnoff without needing to cut across vehicle traffic, and feels much safer to me.”
