New Frontage Road Between Allen and Denney

New Frontage Road Reduces Merging Conflicts

The new southbound frontage road connecting the Allen Boulevard and Denney Road interchanges opened in 2023. The frontage road, in conjunction with the new auxiliary lanes, aims to reduce the amount of merging on the highway which reduces crashes and increases safety and reliability in the area. The interchanges at Allen Boulevard and Denney Road had some of the worst congestion on OR 217. The two interchanges were very closely spaced, which led to merging conflicts and crashes.

The frontage road is southbound-only and is located adjacent to the highway. It works similarly to the frontage road to the north connecting Canyon Road and Beaverton Hillsdale Highway. We also widened both the Allen Boulevard off-ramp and the Denney Road on-ramp to accommodate for the increased traffic on those two ramps.

Using the New Frontage Road

  • For drivers heading to OR 217 south from SW Allen Boulevard: Use the frontage road to travel south and merge onto the highway via the SW Denney Road southbound on-ramp.
  • For drivers heading to SW Denney Road from OR 217 south: Use the SW Allen Boulevard off-ramp to the frontage road. Use the new frontage road to travel south to SW Denney Road.
