The Main Avenue Streetscape and Downtown Commons improvements will be implemented to enhance downtown Twin Falls and support economic development and revitalization. Improvements will include:

  • New sidewalks and paving from street curbs to building faces
  • New street paving and storm drainage facilities
  • Upgraded and expanded street lighting
  • New street trees with better visibility of business signs and store fronts
  • New landscaping and irrigation
  • Festival street areas designed for special events
  • Downtown Commons (Rogerson site): new splash pad (spray play area), concert area, and public restrooms

The project is generally being funded through the Twin Falls Urban Renewal Agency to enhance Downtown for redevelopment and economic revitalization. Main Avenue will be improved for five blocks, from Fairfield Street to Jerome Street. The Hansen Street extension will connect between 2nd Avenue E to 2nd Avenue S, which will enhance access to available parking in the Downtown and enhance vehicle, cyclist, and pedestrian connectivity to destinations north and south of Main Avenue. The Downtown Commons improvements will create a new signature public plaza at the Rogerson site in the heart of Twin Falls. More details related to these planned improvements are listed below.
