Construction for the planned Portland-to-Milwaukie light-rail bridge begins July 1, according to a press release from transit agency Trimet. The light-rail line is expected to open in September 2015.
will begin its geotechnical exploration of land around the bridge next week in an effort to gather data for the design of the bridge’s foundation.
The company will drill in the area around the south end of the Eastbank Esplanade to look at subsurface and seismic conditions in the area where the foundation of the new bridge will go, said Tom Ginsback of Northwest Geotech. The company is still waiting for permits to begin drilling, he said.
Part of the esplanade will be shut down to bicyclists during the work period, expected to last from Feb. 2 to Feb. 11, but pedestrians will still be able to use the area.
A map of the detour is available on TriMet’s website (PDF), and signs will be posted in the area.
