PennDOT originally wanted to close the Fort Pitt Bridge and Tunnel over two construction seasons in the early 1990s but reconsidered after getting an earful from everyone from elected officials to business owners.
The new strategy spread the work over 11 years to minimize problems for drivers and commerce. Meantime, PennDOT has improved alternate routes and the Port Authority has opened the West Busway in time for the most disruptive phase: closing the outbound bridge and tunnel this year, and the inbound bridge and tunnel next year.

Granite-and-metal facades at both portals of the Fort Pitt Tunnel were replaced while traffic was detoured via the West End on weeknights.
$3.8 million

Piers supporting the Fort Pitt Bridge and most ramps were repaired without any disruption to traffic. $2 million
1997
Bridge ramps to and from West Carson Street were closed, one at a time, for reconstruction.

Bridge was restricted during off-peak hours while temporary repairs were made to the bridge decks so they would hold up until now.

The outbound half of the "portal bridge" between Fort Pitt and Fort Duquesne bridges was repaired, as were exit ramps to Liberty Avenue and the Boulevard of the Allies.
