Work started last week on the installation of high tension cable to keep vehicles from crossing the median on Interstate 81.

A contractor for the Pennsylvania Department of Transportation started a safety improvement project last week to install high-tension cable median barriers along Interstate 81 in Franklin County. The purpose of the cable barrier is to help prevent errant vehicles from completely crossing the median area and colliding with vehicles traveling in the opposite direction.

Work got under way along I-81 in Antrim Township as crews prepared to install the concrete foundations and steel posts before attaching the high-tension cable.

The $1,989,844.68 contract was awarded to Nationwide Construction Group to install more than 113,713 linear feet or 21.54 miles of high-tension cable median barrier along I-81 in Franklin County.


There are 14 sections of high-tension cable median barrier – ranging from 768 to 21,463 linear feet – to be installed along I-81 from just north of the Pennsylvania Welcome Center to the Franklin-Cumberland county line.

Motorists are advised that they may encounter left shoulder restrictions during daylight operations through November.
