At this point, the A19 makes a large deviation from its former route, by bypassing Sunderland from the west. Its former route went near the coast. The 8.75-mile Sunderland Bypass opened as the A108, and was built by W.C. French, with fourteen bridges and five underpasses, with the contract awarded in February 1970. The A108 was also previously the number of an A road in north London, for a re-routed A10 to Hoddesdon. At Herrington the A19 meets the A690 (for Houghton-le-Spring) and the B1286 at an interchange. It is crossed by the B1286. At Offerton and Hastings Hill there is an interchange with the A183 road (for Penshaw and Pennywell). The road crosses the River Wear on the Hylton Bridge, which was built as the A108 in 1975 by W.C. French (Construction) Ltd. At North Hylton, there is an interchange with the A1231 (for Washington and Castletown). It passes the Sunderland Nissan plant on the left, formerly the site of the Battle of Britain airfield, RAF Usworth. It meets the A1290, for Washington, at an interchange, where the road enters the borough of South Tyneside and is crossed by the Great North Forest Trail.
