PennDOT installed color detour signs along Interstates 76, 95, 476 and 676 in the region and across the Commonwealth to help police, emergency crews and PennDOT personnel handle traffic diversions more efficiently and safely in the event of an emergency on the interstate.
PennDOT has installed more than 400 of the signs in Southeastern Pennsylvania since December 2007. The signs enable detour routes to be implemented at a moment’s notice to direct traffic around an incident and then return it safely onto the interstate. In the event of such an emergency, interstate traffic will be advised to follow a particular colored detour sign. PennDOT message boards and media reports will inform motorists of which color detour to take. The signing upgrades and investment in technology are part of PennDOT’s multi-million dollar plan to improve traffic management in the five-county Philadelphia region.
