Overview
WSDOT upgraded seven bridges in north Seattle to current seismic standards.
- 42nd Street reversible ramp to I-5 express lanes
- 45th Street southbound off ramp from I-5
- SR 522, I-5 express lanes reversible ramp (Lake City Way)
- SR 522 on ramp to southbound I-5
- NE 85th overpass
- 117th Street overpass
- NE 195th pedestrian overpass
Crews strengthened 22 bridge columns with steel jackets and added catcher blocks to prevent girders from falling off the bridge piers during an earthquake.
 | Improves Safety
The seven bridges are now able to withstand greater seismic stress caused by earthquakes. This reduces the risk of catastrophic bridge failure. In addition, new concrete median barriers were installed in front of the bridge columns to provide greater protection for drivers on I-5.
