The 520 Bridge Trail will be closed from 11 p.m. tonight (September 27) until 5 a.m. Monday (September 30).
The Bill Dawson Trail, which connects from Montlake Boulevard to Montlake Playfield, will also be closed starting 10 p.m. Friday until the same time Monday.
Speaking of the Bill Dawson Trail, access to the trail via the east side of Montlake Boulevard opened recently. I saw someone biking there the other day who was very confused because he was trying to get to the 520 Trail, not Montlake Playfield. But the new tunnel is quite nice.
