Work crews will be doing further geologic explorations beginning Monday, June 17th as part of the project to replace the aging Irving Avenue and 19th Street Bridge in Astoria. A drilling crew and rig will be working on Irving Avenue collecting test borings for approximately three days. Motorists should expect a one-lane closure during daytime hours where the work is taking place. Traffic control, including flaggers, will be set up on site to direct traffic.
This work is part of the investigation necessary to develop design and construction plans for a new bridge. The current Irving Avenue Bridge was built in 1946 from steel, which typically has a 50-year lifespan. The new bridge will be built to handle safe vehicular, pedestrian, and bicycle passage. Conceptual estimates put the cost of the new bridge at approximately $5 million. The Federal Highway Bridge Program, administered by the Oregon Department of Transportation, will fund 90% of the cost to replace the bridge.
Construction of the new bridge is scheduled for summer 2014. During construction, Irving Avenue will be closed at 19th St and this road closure could last as long as a year. In the meantime technical consultants led by David Evans and Associates under the direction of the City of Astoria will be undertaking a variety of technical analyses and design tasks.
