Two-Way Conversions

Work is underway to remove the inconsistent one-way/two-way street network downtown and transition all downtown streets to two-way travel. This will make the downtown and surrounding districts easier to navigate and help reduce confusion.  Two-way streets also help encourage slower travel speeds, allow for pedestrian and bike accommodations, and support business access/visibility. 

Quick Links

3rd Ave from 1st Street SW - 5th Street SE

Project Improvements

  • Surface improvements on roadway
  • Protected bike lanes on 3rd Ave Bridge, separated by planters and benches
  • Protected bike lanes from 1st Street to 5th Street SE, separated by raised medians
  • Pedestrian bump-outs at intersections between 1st Street SE to 5th Street SE
  • New railroad gates and crossing arms with bump-outs at 4th Street SE

Why Two-Way Streets?

Two-way street conversions are being considered on many existing one-way streets for several reasons: 

  • Livability / Vibrancy: Two-way streets create an urban environment with slower traffic speeds. They also support biking opportunities, makes it easier to access public gathering spaces, and increases business access and visibility. For those visiting downtown districts for events or entertainment, two-way streets are intuitive and easier to navigate.  

  • Safety: One-way streets – especially if they have multiple travel lanes – often encourage higher traffic speeds due to motorists’ ability to pass a slower vehicle, creating unsafe conditions for residential or downtown environments.

  • Efficiency: One-way streets are outdated, and often do not support today’s traffic volumes. Built decades ago before the construction of the interstate, one-way streets were often used to move high volumes of commuter traffic. Today, a large volume of traffic has been pulled off these streets and onto I-380, enabling residential or downtown streets to better serve local destinations.
  • Convenience: Two-way streets are easier to navigate, and cut down on the time it takes to get to your destination. Traffic no longer has to make “loops” around one-way streets, but can take the shortest, more direct route to a home or business.

Features of Downtown Conversions

Pedestrian Safety | Painted Islands

  • Reduces walking distance for pedestrians. 
  • Increases visibility for those trying to cross the street. 

Protected Bike Lanes on 3rd Avenue

  • 3rd Avenue is a primary bicycle route. 
  • Protected bike lanes separate cyclists from moving vehicles
  • They create a more comfortable experience for those riding bikes, and decrease incidents of “dooring.”

Traffic Signals 

  • Signals in the downtown area that have been removed do not meet traffic warrants, which means traffic could be accommodated comfortably by stop signs.
  • Stop signs also help eliminate unnecessary idling and the yielding that comes with waiting for oncoming traffic.
