On November 16, 1984, the Columbia Avenue (now Cecil B. Moore Avenue) bridge near old Temple University Station was found to be unsafe, putting all four tracks out of service north of Market East Station. In December 1984, a temporary bridge opened, allowing service to resume north of Market East Station. Nonetheless, the results of decades of deferred maintenance on the Reading Viaduct between the Center City Commuter Connection and Wayne Junction continued to threaten the right-of-way. In 1992, the bridge was in such poor condition that the bridge inspector actually saw the structure sag every time a train passed over the bridge; further inspection revealed that the bridge was in imminent danger of collapsing.
