US-95 Traffic Operations: No Build 2050

Most intersections on US-95 in Moscow currently operate at an acceptable level of service (LOS). LOS is graded from A to F. Worsening LOS represents increased delays and wait times. We anticipate some specific intersections and single-lane movements will progress to an unacceptable LOS by 2050, our study design year.​

Non-Signalized Intersections

US-95 traffic flow would remain stable, but movements from side streets onto or across US-95 would experience significant delays at:​

  • Rodeo Drive 

  • Morton Street 

  • C Street

  • 1st Street

  • Styner Avenue

  • Southview Avenue

Traffic Queuing

The most frequent vehicle movements on US-95 are near capacity and will continue to worsen without improvements:​

  • Northbound US-95 to westbound Third Street.

  • Westbound from Jackson Street (US-95) onto SH-8. Queuing on Jackson Street will cause delays on College Street.

SH-8 Traffic Operations
Most intersections on the SH-8 corridor between the Washington/Idaho border and Troy operate at an acceptable LOS. By 2050, about a third of the study intersections will deteriorate to an unacceptable LOS.

Capacity at Signalized Intersections 

SH-8 traffic demand is anticipated to exceed intersection capacity, leading to significant delays for various turning movements at:​​

  • WA-270 & Airport Road

  • SH-8 & Perimeter Drive/Farm Road

  • SH-8 & Stadium Drive/Peterson Drive

  • SH-8 & Line Street

Delay at Non-Signalized Intersections

Side street traffic at the following non-signalized SH-8 intersections is anticipated to experience significant delay:​

  • SH-8 & 3rd Street/Lieuallen Street

  • SH-8 & Styner Avenue/White Avenue

  • ​SH-8 & Mountain View Road
