In anticipation of the roadway widening project the City began work to relocate a waterline along the project limits. The waterline relocation project began on April 20, 2016 and work progressed thru June 7th. The reconstruction and widening of Grandview Drive from Skyline Drive to Saturn Avenue began on August 1st  and will run through November of 2016.

Work that has been completed to date includes:

  • waterline relocation
  • phone relocation on the north side of Grandview
  • construction of a storm water infiltration system that will hold 900 cubic yards of water at a depth of 16 feet beneath the roadway
  • construction of the storm sewer lines
  • construction of the north roadway retaining wall
  • roadway base and paving (bottom lift) on the north half of the roadway

Traffic has been shifted to the north paving under it’s current configuration and will remain in this configuration until paving, utility adjustments and pavement markings on the south side of the roadway are complete. Remaining work includes retaining wall construction on the south side of Grandview, curb, gutter and sidewalk installation, roadway excavation and paving on the south side of Grandview and utility adjustments/striping.  Paving is scheduled to be complete (weather permitting) in November. The speed limit is reduced to 25 MPH, and traffic should expect periodic lane closures around the work zone throughout construction. This federally funded project will provide roadway improvements including the reconstruction of the roadway, widening of Grandview to five lanes, a 12 foot wide shared use pathway on the south side of the roadway, and a sidewalk on the north side of the roadway between Skyline and Saturn. During all construction activities, watch for equipment and workers, follow all traffic signs and flaggers, and reduce speeds to posted limits. For questions, call Public Works at (208) 612-8250. 



Thompson Paving has closed the east side river walk, along Riverside Drive from “E” Street to Vissing Circle, to pedestrian traffic for pathway reconstruction. Pathway users are encouraged to follow the detours mapped out through the end of September. The impacts to traffic along Riverside Drive include lane and shoulder closures. Pedestrians and cyclists are encouraged to follow the pedestrian route shown on the Detour Map.
