Geiger Field Interchange Reconstruction


Welcome to the Geiger Field Interchange improvement online open house. This is the second phase of two projects along Interstate 90 on the West Plains to improve efficiency. The first project began construction in 2019 at the Medical Lake/SR 902 interchange. This second project will improve the Geiger/Grove Road interchange.


Due to the increase in traffic at the Geiger interchange, the existing stop-controlled intersection is no longer meeting the operational needs. With the significant growth on the West Plains from new businesses and residential developments in the area, the interchange at Geiger is in need of capacity improvements. Currently, there are three stop-controlled intersections that will be improved to allow traffic to move more efficiently through the area.

  • Geiger Boulevard and Grove Road
  • Grove Road and westbound Interstate 90 on and off-ramp terminals
  • Grove Road and the eastbound Interstate 90 on and off-ramp terminals


This project features three new roundabouts to replace the current stop-controlled intersections. Multi-lane roundabouts will be constructed at the Grove Road and Geiger Blvd. intersection, and the intersection of Grove Road and the westbound I-90 on and off ramps. A single lane roundabout will be constructed at the intersection of Grove Road and the eastbound I-90 on and off ramps.

This project will also include the modifications to several of the interchange ramps. This includes the removal of the westbound on loop ramp, and the installation of ramp meters on the eastbound on-ramp and the eastbound on loop ramp. An eight-foot wide shared use path will be added along both Geiger Blvd. and Grove Rd. This will improve the bike, walk and roll access and safety in the interchange vicinity.

This project is currently scheduled to go to advertisement in October 2020. Construction is scheduled to begin in the spring of 2021 and be completed by fall 2021.


The Geiger/Grove Interchange Reconstruction project is primarily funded with $11.5 million through the Connecting Washington package passed by legislatures in 2015.

An additional $3.8 million was awarded to the Geiger/Grove interchange project through a joint Federal BUILD Grant (PDF 8 MB) with WSDOT, Spokane County, the City of Spokane, Spokane Transit Authority (STA), Spokane International Airport, Spokane Regional Transportation Council and the West Plains/Airport Public Development Authority.
