The interchange was designed and built when the surrounding area was still rural. The problems that will be addressed by this project are:
- The outdated interchange design creates merging and weaving issues on the two intersecting highways.
- This area has been identified as a high crash location by ODOT's Safety Priority Index System (SPIS) in 2012 and 2014.
Changes will be made to the Interchange Configuration
- Eastbound drivers exiting Beltline to northbound Delta will pass through a new traffic signal.
- The exit ramp from Beltline to northbound and southbound Delta will be extended to the Willamette River Bridge. This will allow traffic to exit Beltline sooner.
- A new bridge will take northbound Delta traffic onto westbound Beltline (via the loop ramp). The new bridge will be constructed next to the existing overpass specifically for this traffic.
- A new lane will be added to the loop ramp for westbound traffic will be reconstructed to provide two lanes.
- A new ramp meter will be installed at the end of the loop ramp, at the merge with westbound Beltline. The ramp meter will create space between cars and trucks entering the highway, allowing traffic on Beltline to flow more smoothly.
Travel will change through the interchange as ramps are improved:
- Loop ramp from eastbound Beltline to northbound Delta will be removed.
- Off-ramp from eastbound Beltline to southbound Delta will be reconfigured.
- Loop ramp from northbound Delta to westbound Beltline will be reconstructed.
- On-ramp from Goodpasture Island Road to nortbound Delta will be reconfigured.
Construction has begun and is expected to last through 2021
