Lane closures are limited to nighttime hours (10:00 p.m. to 8:00 a.m. Friday through Sunday on Morrison Bridge; 10:00 p.m. to 6:00 a.m. on other roadways), requiring 72-hour notice to ODOT Traffic Management Operations Center, Multnomah County Bridge Maintenance, and Portland Bureau of Transportation. The contractor must obtain a City of Portland Temporary Street Use Permit and coordinate with TriMet regarding bus stop impacts.

The contractor must work continuously seven days per week once work begins.
