ITD experiments with solar-powered pavement markings
February 28, 2018
The unusual amount of sunshine this winter has allowed the Idaho Transportation Department to work on their innovative thinking and to experiment with a few alternatives to typical highway work. The most recent options are solar-powered pavement markings, which ITD has installed on an experimental basis along short stretches of US-30 in Pocatello. These solar-powered markers are intended to increase the visibility of raised curb islands for drivers.

Another section of US-30 in the Pocatello area will soon be fitted with the new special markers also.
ITD purchased 600 units and earmarked 100 for each of their six regional offices. The southeast Idaho office was the first to have them installed, but our ITD North Idaho District 1, will eventually have them installed somewhere within the region.

"This [Pocatello] location was decided upon as a safety improvement due to lack of streetlights in this area and to help denote where there is curbing. The markers are lit and reflective, making them a good channelizing device in the dark," ITD southeast Idaho Operations Manager Steve Gertonson explained. The markers store up solar energy during daylight hours, then use that to power LED lights in the markers at night.

ITD southeast Idaho Maintenance Foreman David Petersdorf said he’s already received numerous calls from the public saying they like the new markers.
