During reconstruction of Pittsburgh's Interstate 376, traffic and passenger diversion efforts, more extensive than ever before, were undertaken. Eight percent of the $62 million spent in rebuilding 6.5 miles of expressway was spent diverting vehicles or passengers. Steps taken included reactivating a dormant passenger rail service, building and park-n-ride lots, instituting express bus service on existing and new routes, building on-ramps to provide priority access for multi-occupant vehicles to the construction zone, third party vanpools, programmable message signs, extensive traffic operations improvements, and delaying twelve other highway construction projects in the area until this one was done. Also unique were the very careful and extensive studies of effectiveness of each rerouting activity. The project is a national model in attempting to minimize traffic delay due to highway construction.
