PennDOT will begin a 14-month project next week to install raised pavement markers on several state highways in Montgomery County.
The reflective markers are installed along center lines, edge lines and ramps to improve visibility for drivers at night and in rain, fog and snow.
Work will start on Sunday, Aug. 12, from 10 p.m. to 5 a.m. Monday, Aug. 13, along I-76 between the on-ramp to Route 320 and City Avenue in Montgomery County.
In Montgomery County, the markers also will be placed on Route 309 and Gulph Road.
During installation, crews will occupy one lane to conduct a slow-moving operation. Motorists are advised to expect slowdowns. The operation is dependent on the weather.
D.W. Miller, Inc. of Huntingdon, Pa. is the contractor on the federally-funded project, which is scheduled for completion by October 2013.
The markers are installed in notches cut into the pavement surface and held in place by special epoxy glue. The lens, which has a protective metal casting, sits about one-quarter inch above the surface of the roadway.
The raised pavement markers require lenses to be replaced every two to three years for maximum performance.
