Sarah Mildred Long Bridge

This is a vertical lift bridge crossing the Piscataqua River, connecting Maine and New Hampshire in the US

  • Actual cost $158M   (£122M)
  • Vertical lift bridge with 91m long lifting span
  • Completed 2018 – built in 36months
  • Total length 850m
  • Clearance when open 41m
  • Rail,  road (on different levels!)  and cycle

The total length is double the longest possible over water distance at Rotherhithe  and 3x that of the Northern alignment

Here is another example of a massive road/rail bridge of comparable/greater size costing less than ¼ the worst case estimate for our ligtweight pedestrian/cycle bridge!
