Lair Hill Neighborhood Traffic Access Management Project

 Ross Island Bridge Onramp

Project Description: This project is a nine-month pilot project designed to reduce cut-through traffic in the Lair Hill area south of downtown, keeping regional car traffic on safer routes to head east on the Ross Island Bridge. The project will limit through traffic on a few narrow residential streets from Monday Dec. 16, 2019 through Sept. 1, 2020.

The changes were prompted by requests from residents along the affected streets, as well as the South Portland Neighborhood Association, (SPNA) for PBOT to help address congestion and unsafe driving behavior on SW Corbett and SW Kelly avenues. The traffic is especially heavy during evening rush-hour times, when people driving from Interstate 5, downtown Portland and areas south of downtown are driving to the bridge.

The following cut through routes will be closed by the project:


SW Kelly Ave, between SW Whitaker and SW Curry:

- Close northbound access

- Purpose: prevents commuter traffic from using SW Kelly to access the eastbound bridge ramp on SW Kelly.

SW Whitaker St, between SW Kelly and SW Corbett:

- Close eastbound access

With the uncertainties surrounding travel and COVID 19, ODOT has agreed to extend the End of Plan Development/ Public Review until March of 2021.  Evaluation data will be gathered in late 2020 or early 2021 for analysis, depending on how quickly traffic returns to normal.
