Interstate 84 will be closed to all traffic between I-5 and I-205 this Friday night, Jan. 12.

While the full closure takes effect at 11 p.m., sections of I-84 will lose a lane as soon as 8 p.m. Some on-ramps and off-ramps will also close at that time.

"During the closure, crews will install new electronic sign structures at two different locations on I-84," reports KOIN 6 News, our media partner.

Motorists hoping to get an early start can return to Interstate 84 as early as 6 a.m. Saturday, Jan. 13. The Oregon Department of Transportation will reopen all lanes at that time.

Travelers heading out for Friday night festivities are advised to plan accordingly. Here's a list of all major on- and off-ramp closures, as reported by KOIN:

• OMSI/Central Eastside Industrial District off-ramp from I-5 northbound

• All ramps from I-5 and I-205 to I-84

• Ramp to I-84 eastbound from the Morrison Bridge
