During the ramp closures, travelers will need to use an alternate route
VANCOUVER – Travelers who use Interstate 5 in Vancouver will need to plan ahead for daytime delays.
Beginning Monday (Sept. 30), the Washington State Department of Transportation’s maintenance crews will pave the off- and on-ramps at Northeast 78th and 99th Streets, smoothing the driving surface and extending the life of the roadway.
What to expect
The following ramps will be closed daily, from 9 a.m. to 3 p.m.:
- Monday, Sept. 30: Northeast 78th Street off-ramp from northbound I-5 at milepost 4.
- Tuesday, Oct. 1: Northeast 99th Street off-ramp from northbound I-5 at milepost 5.
- Wednesday, Oct. 2: Northeast 78th Street on-ramp to southbound I-5 at milepost 4.
- Thursday, Oct. 3: Northeast 99th Street on-ramp to southbound I-5 at milepost 5.
During the ramp closures, travelers will need to use an alternate route. Because paving work is weather dependent, it may be paused at any time, due to inclement weather.
To keep both travelers and maintenance crew safe, travelers are asked to slow down, pay attention and use caution near the work zone.
