[5] [6] [7] At 37.9 kilometres (23.5 miles), it has the longest underwater section of any tunnel in the world and is the third-longest railway tunnel in the world. While designed to accommodate trains travelling at up to 200 kilometres per hour (120 miles per hour), for safety, trains are restricted to a top speed of 160 kilometres per hour (99 ...

Several engineers have designed bridges on various alignments and with differing structural configurations. A proposal by Professor T.Y. Lin for a crossing between Point Oliveros and Point Cires featured deep piers, a length of 14 kilometres (9 miles), 910-metre-tall (3,000 ft) towers, and a 5,000-metre (16,000-foot) span, more than twice the length of the current longest bridge span.

A tunnel could be built between Sweden and Åland, about 50 km (30 mi) long, and 100–200 m (330–660 ft) deep, with the lowest depth around Märket, a little detour. The area between Åland and Finland is shallow with many islands, able to be connected with bridges - some of which already exist.
