We built a new 470 foot long bridge on SR 99 where it crosses over Spokane Street in Seattle. The new bridge is constructed of lightweight Geofoam blocks capped with concrete.
The new bridge replaced a timber bridge that was built in 1959. The timber supports of the old bridge were rotting and splitting apart.
The new bridge is designed to meet current seismic standards to better withstand earthquake activity.
Reduced fire risk
Removing the old timber supports eliminates the threat of the wooden beams catching fire.
A new barrier was installed between eastbound and westbound traffic
| Protects Environment
We removed timber that was coated in creosote. This reduces the risk of contaminates entering stormwater drains and pollutants from being released into the air in the event of a fire.
