Geiger Field Interchange Reconstruction

Introduction

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.

Background

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.

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

Improvements

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.
