Update: Apparently they found the concrete. The bridge will be closed Tuesday to Friday.

The Burnside Bridge will be closed to road traffic from 8:00 pm on Tuesday, May 2 until 6:00 am on Friday, May 5 to allow a contractor to pour a concrete sidewalk on the new lift span deck.

Update: the closure has been cancelled do to a ‘concrete supply issue’. Maybe a Chinese project outbid us…

Look for alternate routes through Monday, that concrete has to cure:

The Burnside Bridge is scheduled to be closed to road traffic from 8:00 pm on Friday, April 28 until 6:00 am on Tuesday, May 2 to allow a contractor to pour concrete for a section of sidewalk on the new lift span deck. The bridge is in the midst of a two-year repair project which will replace the lift span deck and repair or replace parts that open the 79-year old bridge.

The bridge closure is needed for the contractor to pour the sidewalk and for the new concrete to harden without vibrations from traffic, which could lead to cracks in the new sidewalk.

Last weekend the bridge was closed for the contractor to pour concrete for the first section of new deck. Construction specifications require the new concrete deck to cure for one week before concrete is poured for the adjoining sidewalk.

The closure will impact motor vehicles, bicyclists and pedestrians. During the closure TriMet bus routes 12, 19 and 20 will use the Morrison Bridge. The bridge will also be closed to river traffic from 8:00 pm on Friday until 5:00 am on Saturday. The bridge will remain open to pedestrians and bicyclists except for during the concrete placement on Saturday morning.

The work is weather dependent. If heavy rains prevent work on Friday night, the work will be rescheduled for Saturday or the first day when weather conditions permit.
