Tay Road Bridge Tay Road Bridge The Tay Road Bridge carries the A92 road across the Firth of Tay from Newport-on-Tay in Fife to Dundee in Scotland, just downstream of the Tay Rail Bridge. At around , it is one of the longest road bridges in Europe, and was opened in 1966, replacing the old Tay ferry. As part of the modernisation projects of the 1950s, a road bridge across the Tay had been considered for several years. In August 1958 a traffic census and test bores were taken to locate the most suitable crossing for the bridge. The bridge was designed by
Tay Rail Bridge of the top of the section below. The joint was then secured by bolts through matching holes on lugs (Crumlin) or flanges (Belah) on the two sections. This 'spigot and faucet' configuration was used (apparently without machining) on some Tay Bridge pier columns, but on some the bolts were relied upon to ensure correct alignment. (In the event, the joints were made using undersized bolts. This gave greater tolerances when assembling the column, but the less positive alignment of the column joints as initially assembled and after any subsequent 'working' of the joint would have weakened the column).
