PORTLAND, Ore. (KOIN) — The OR 43 ramps leading to I-5 SB, Lake Oswego, downtown Portland and the Ross Island Bridge will close for more than 2 weeks starting Sunday, August 14.

Know your detour – ODOT map generator.

ODOT crews need to pave and make upgrades to those ramps, where rebar is exposed. The closure begins Sunday, August 14 and will continue around the clock through Wednesday, August 31. (See map below.)

Ramps affected:

– The northbound OR 43 ramp to SW Kelly and Hood Avenues.
– The northbound I-5 off-ramp (exit 299A) which leads to OR 43, southbound I-5, Lake Oswego, downtown Portland, and the eastbound lanes of the Ross Island Bridge.

– The westbound Ross Island Bridge ramp to SW Hood Avenue, which leads to southbound I-5 and Lake Oswego. SW Corbett Avenue will remain open.

The long duration of the closure will allow the new concrete overlay to have time to harden before the ramp deck is re-opened to traffic. The new concrete is more durable, more impervious to water and lasts longer than the other concrete mixes. Roughly 15,000 vehicles a day use this section of road to reach downtown Portland and the Ross Island Bridge.

Suggested detour routes:

From Westbound Ross Island Bridge to OR43 South.
From SW Kelly Avenue, continue westbound to SW Arthur St. Turn right on SW 1st Avenue and then turn right on SW Sheridan St. Turn right to SW Naito Pkwy and take the exit to OR 43 and Lake Oswego.

(Follow the existing “OR43/Macadam Avenue – Lake Oswego” green guide signs on SW Naito Pkwy and SW Kelly St.)

From SW Macadam Avenue north of SW Curry St to I-5 South.
From SW Macadam Avenue, enter the on-ramp to I-5 North and take Exit 300. Then take the OMSI/Central Eastside exit. Turn right on SE Water Ave and then left on SE Taylor St. Turn left on SE Grand Ave. Turn left on SE Morrison St to cross the Morrison Bridge.
