ODOT will soon begin construction on a project to repair a number of freeway ramps along Interstate 405. These repairs will improve the condition and maintain the long-term safety and use of this heavily traveled freeway.
Construction begins in the spring of 2019 and lasts through the fall of 2020. This work requires closing lanes, shoulders and on- and off-ramps along I-405, U.S. 30, Interstate 5 and U.S. 26.
The actual work will take place on I-405 on either side of the Fremont Bridge and on the ramp from I-405 north to U.S. 26 west. Three freeway ramps will receive new concrete surfaces. The on- and off-ramp closures are needed to maintain a safe work zone for construction staff.
Traffic impacts include nighttime, weekend and extended closures of on- and off-ramps along I-405 and I-5 as well as lane and shoulder closures. Some sidewalks, lanes and parking on local roads will close as well.
In order to complete the work, on- and off-ramps in the project area will experience intermittent closures, including nighttime, weekend and extended closures. (See maps below for ramp closure locations.)
Approximately 21 weekend closures are expected throughout the project. Some weekend ramp closures will happen simultaneously. This number could change based on weather or site conditions. Weekend closures will start as early as 8 p.m. on Friday and will end by 10 a.m. on Monday.
Multiple overnight closures of on- and off-ramps and lanes will take place for nighttime construction work. Night work is needed in order to minimize traffic impacts during the day.
During summer 2019 and summer 2020:
11-day closure: US 30 east to I-405 south
14-day closure: US 30 east to I-405 north
Extended closures are needed to install new concrete surfaces.
ODOT will continue to send project updates, including ramp closure dates and detour routes, as the project continues. Closer to construction, you can find the most current project information at www.i405ramps.org.
