Traffic Delays Expected for Next Two Weeks on OR 43

It's going to be a tough two weeks for all drivers who use the ramps leading from OR 43 to the Ross Island Bridge, I-5 Southbound, downtown Portland, and Lake Oswego.

Crews from the Oregon Department of Transportation need to work on those ramps where rebar has been exposed. They will repair the rebar as well as pave and make upgrades to those ramps.

The work is expected to last until August 31st.

More information can be found on this website set up by ODOT.

According to ODOT:

The closure will affect travel on these routes:

• OR 43 (Southwest Macadam Avenue) ramp to Southwest Kelly and Southwest Hood Avenues.

• Northbound Interstate 5 off-ramp (exit 299A) leading to OR43 (Southwest Macadam Avenue), southbound I-5, Lake Oswego, downtown Portland and the Ross Island Bridge.

• Westbound Ross Island Bridge ramp to SW Hood Avenue which leads to southbound I-5 and Lake Osweg

The OR43 (SW Macadam Avenue) ramp connecting to Southwest Kelly Avenue and Southwest Hood Avenues will be closed day and night (all hours, seven days a week) from Aug. 14 - 31, 2016, to replace the deck and allow time for concrete to cure. I-5 Northbound exit 299A leading to southbound I-5, Lake Oswego, Ross Island Bridge and downtown Portland will also be closed.

*The OR43 (SW Macadam Ave) ramp connects to southbound I-5, Lake Oswego, downtown Portland and the Ross Island Bridge. *

Additional nighttime closures may take place before and after the full closure (Aug. 9 - Aug. 13 and Sept. 1 - Sept. 3, 2016) as crews prepare the work site and perform other needed maintenance in the area.

Please note: The schedule is subject to change due to weather and site conditions.
