This article is about the former B7054 in central Greenock. For the current B7054 to the south of Greenock, see B7054.
West Blackhall Street (on the former route of the B7054)
The original line of the B7054 was much closer in to Greenock town centre than the current route, and the route varied a little over the years. Identified, but unnumbered on old one-inch maps, it is now known from larger-scale mapping that the B7054 previously ran along West Blackhall Street, parallel to what is now the A770 in central Greenock. Originally it appears that the A742, as was, then followed Cathcart Street to meet the A8 Rue End Street. Later, however – when the A742 was re-routed to roughly its current line (now it has been renumbered A78) – it crossed the B7054, which was also extended eastwards along Cathcart Street, making it a loop off the A8.
Today, the whole area around this route has been heavily rebuilt, with Greenock's new shopping precinct obliterating the central section of the old road. What is left is the western end of West Blackhall Street and the eastern end of Cathcart Street (both now unclassified), but there is no road between the two except the current line of the A78, which runs at right angles to meet the A8.
