“As of today, it’s fully functional,” he said.
WSDOT combined the drainage project with the installation of a Variable Message Sign board, which gives traffic information to motorists.
The last bit of work is the installation of equipment that pretreats the water before it flows into the pond. That site will eliminate the larger, bulky material that comes off the roadway and causes flooding. Occasionally maintenance crews will vacuum the debris that collects in the vault.
Reck said that WSDOT will likely employ similar solutions along other parts of Highway 503 if needed.
