The State Route 520 westbound on-ramp at 84th Avenue Northeast closed Wednesday and may not reopen for up to two weeks.

A contractor working on the SR 520 bridge replacement for the state transportation department drilled a hole into a stormwater pipe under the highway by accident and is now working at their expense to fix it.

During the closure, motorists will need to take the Bellevue Way on-ramp to access SR 520 westbound lanes.
