Two-Way Conversions

2017-18 Two-Way Conversions Timeline updated July 2017Two-way streets, bike lanes, transit options, and pedestrian facilities have been intentionally incorporated to support the ongoing development of the downtown. Two-way streets are also easier to navigate and help reduce speeds. 

This summer and fall, work will continue on the two-way conversions and bring us significantly closer to a more consistent two-way network.

Railroad Crossings
Continued collaboration with Union Pacific Railroad means that safety improvements will also take place this year and next at the railroad crossings, including the construction of new arms and gates. These are necessary to support two-way traffic and will also help secure a quiet zone. UPRR will coordinate these improvements at 2nd, 3rd, 4th, and 5th Avenues.

  • 2nd Avenue, 4th Avenue, and 5th Avenue: 2017 - 2018

Benefits of Two-Way Travel:

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

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.
