Ada County Highway District

Cole Road, Spectrum to Century Way Medians

Construction Update as of 4/23/18: Concrete work near Spectrum began on April 22nd. Work will be done at night or on weekends with lane closures.

Starting the end of February/early March construction will begin in the Cole and Overland intersection area for safety improvements. Electrical work began in February and all construction is anticipated to be complete in May 2018.

Traffic and Construction Impacts
Most of the work is anticipated to be done at night and is expected to occur between 8 p.m.-6 a.m. During the night work there will likely be temporary closures to the existing right turn lanes at the Cole and Overland intersection, as well as closures at the intersection. There may also be the following impacts: lane restrictions, general construction noise, dust, equipment back up alarms and ground vibration.

Please note that the contractor will coordinate with businesses and property owners to maintain access during construction.

Work will also include replacing the free running right-turns at the Cole and Overland intersection, as well as other safety improvements at the intersection.

General Description:

  • Replace existing candlesticks on Cole Road between Spectrum and Century Way with curb and medians.
  • Add additional curbs and medians for safety.
  • Construct a median on Century Way (northern portion) where street intersects with Cole Road to prevent left turns from Century Way onto Cole.

All businesses will continue to have left turn in access to their property either from Cole Road or adjacent streets such as Century Way or Spectrum.

Why is ACHD doing this project?

  • ACHD has been incrementally adding candlesticks to this section of Cole Road as safety issues have arisen. The candlesticks have helped increase safety by limiting left turns across a busy five-lane roadway. Unfortunately, candlesticks don't hold up very well and ACHD would like to replace the candlesticks with curb medians.
  • ACHD has also evaluated the advantages and drawbacks to adding curb and medians to other areas along this section of Cole Road and have determined that it would be beneficial.
  • Fortunately, the Century Way loop provides a natural route for most businesses to safely access Cole Road.
