The A19 Tees Viaduct or Tees Flyover is a high level six-lane dual carriageway road bridge in the North East of England carrying the main A19 trunk road north–south across the River Tees. The bridge is located between Middlesbrough and Stockton-on-Tees just north of the A19's interchange with the A66 trunk road and carries the north–south traffic through Teesside avoiding the main towns but is also used extensively by local traffic.Wikipedia
