The Broadway Bridge is more than 100 years old and in need of replacement. We will demolish and replace a 100-feet span by 100-feet wide bridge over the Burlington Northern Santa Fe (BNSF) railroad main line. The bridge span is located on Broadway between Hewitt Avenue and California Street.
Current weight restrictions:
Effective June 19, 2014, the City Engineer has extended a weight-limit restriction to all lanes of Broadway between Hewitt Avenue and California Street. Vehicles weighing more than 11 tons must use alternate routes:
Signed truck detour route
Alternate truck routes
Contract Awarded to Interwest Construction, Inc. October 1st, 2014
Begin Detour Route construction: November 2014
Begin Bridge Demolition: January 2015
Complete Construction: Fall 2015
Why will it take so long?
· No over-track work allowed while trains are running – 44 freight trains on average per day
· No over-track work allowed from October to December – BNSF major freight season restriction
· Total demolition and new construction of the bridge with new foundation and abutments (as opposed to swapping out a bridge span like the temporary Skagit River bridge)
· Different vertical alignment – for improved sight distance and railroad clearance
