Two Way Conversions

Two-way street conversions have been considered for several years as part of the City’s efforts to support downtown as a place of activity, not just as a pass-through route. Cities across the country have seen firsthand the benefits of shifting to two-way streets and introducing more multi-modal transportation options. Two-way streets are also easier to navigate and help reduce speeds in residential neighborhoods. 

Benefits of Two-Way Travel:

  • Increase in retail
  • Increase in pedestrian safety and activity
  • Slower traffic speeds
  • Opportunity to bike, drive, or walk 
  • Support for residential, downtown living

Pedestrian Safety | Painted Islandspainted pedestrian areas downtown

  • 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 and cuts through the core of downtown, making it an ideal Protected bike lane with signagelocation for the addition of bike lanes.
  • The new lanes also connect to already existing bike lanes on 3rd Avenue, closing the gaps in our bike network.
  • Protected bike lanes come with many safety benefits. Learn more about Protected Bike Lanes and other pavement markings

Traffic Signals 

  • Traffic volumes have decreased downtown. Those visiting downtown are often traveling to a destination, not as a pass-through route. 
  • The signals in the downtown area that are being 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.

Working with Railroad to Close the One-Way Gaps

It has always been the City's goal to complete these conversion projects as quickly as possible, and remove remaining one-way segments. The railroad that cuts through the heart of downtown requires new crossing arms and gates to support two-way traffic. The City is working with Union Pacific and is actively pursuing the creation of conceptual drawings for these crossing improvements. Staff will determine construction costs and develop a prioritization plan for moving forward.
