Bridge closure and test pile work

Field Work Update - September 16

Reminder: Bridge closed on Sunday, Sept. 18

The Sellwood Bridge will be closed to motor vehicles on Sunday from 7 a.m. until as late as 3 p.m. while a contractor removes small concrete samples from the bridge deck in preparation for the relocation of the bridge in 2012. The river spans will be moved 40 feet north late next spring to create a detour bridge and make space for construction of the new bridge. The bridge will be open on Sunday for bicyclists and pedestrians. Motor vehicles will need to use alternate crossings such as the Ross Island or I-205 bridges. Potholes on the bridge will be repaired and streetlight bulbs will be changed also on Sunday.

Test pile work in river in late September

The contractor plans to install and remove six test piles in the river between Monday, September 27 and Friday, October 6. The purpose of the work is to test the piles that will be installed in December to support the river columns for the detour bridge. The test piles will be installed about 40 feet north of the existing river piers. The contractor plans to set up on September 27 and begin installing piles on September 28. Work hours will be between 7:30 am and 5 pm. The contractor will vibrate the piles into the river bottom to a depth of roughly 100 feet and then use an impact driver to test their full depth. The piles will all be removed by the end of the test in early October.
