Stop me if you've heard this story before ...
A bike rider traveling westbound on Beacon Street. A driver stopped eastbound, hoping to turn left across westbound traffic. A gap opens in car traffic. The driver doesn't see the bike rider, turns left, and hits the bike rider.
According to a just-obtained police report*, this is exactly what happened last September at Beacon Street and St. Thomas More near the BC campus. In this cases, the driver hit the biker square, tossing her up onto the windshield.
[The driver] stopped in the road heading East on Beacon Street, waiting to turn left on St Thomas More Rd. A break in the auto traffic occurred and [the driver] accelerated into the turn. At this time [the biker] was proceeding West on beacon on her bicycle and the two collided "head-on". [The witness] stated that [the biker] smashed into the mini-van's windshield and then rolled several times on the street.
It's not clear from the police report whether there was stopped westbound traffic that blocked the biker from the view of the turning car, but it would not be surprising. That's a frequent occurrence at that intersection. Traffic backs up, so westbound traffic stops so it doesn't block the box. The stopped westbound traffic blocks the view of bikes in the bike lanes. The dynamics of the intersection encourage westbound cars turning left onto St. Thomas More to take advantage of the gap and scoot through.
And, this is an intersection with the latest and greatest in bike lanes. There are official bike lanes on both sides of the intersection and dashed lines through the intersection connecting them. Bike lanes are not going to fix the underlying problem of hidden bikes and anxious drivers. This intersection, like the Beacon St./Grant Ave. intersection really demands a more thorough solution.
*Finally got around to BPD HQ to request the report.
