Our preliminary analysis of the intersection indicates that a right-turn lane on eastbound Cornell Road onto southbound Barnes Road would:

  • Reduce congestion significantly and enhance mobility.
  • Improve safety and reduce crashes. (Up to 30% of crashes on Cornell Road occur in eastbound congestion.)
  • Reduce vehicle backup west of Murray Boulevard (eastbound traffic) during the afternoon/evening rush hour.
  • Provide additional cyclist protection from vehicles turning right.
  • Potentially reduce traffic cutting through neighborhoods to avoid congestion on Cornell Road.
  • Improve TriMet bus service reliability.
     

An eastbound turn lane also would:

  • Eliminate one block of on-street parking and the curb extension on the south side of Cornell Road (west of Barnes Road).
  • Add bicycle-vehicle weaving challenge for cyclists navigating the new right-turn lane.
  • Require possible relocation of  the bus stop on the south side of Cornell Road, west of the intersection.
  • Impact utilities, resulting in cost and construction impacts.
  • Require possible reconstruction of the traffic signal, resulting in cost and construction impacts.
  • Result in increased pedestrian crossing distance.
