Pönttövuori tunnel

The Pönttövuori tunnel is a rail tunnel under the Pönttövuori hill, on the Jyväskylä–Pieksämäki railway line, in Laukaa, central Finland, some 17 kilometres (11 mi) east of Jyväskylä.

[1][2] The original, now disused, tunnel was completed in 1918, and is 1,223 metres (4,012 ft) in length.

[3] It cost slightly over 2m Finnish markka to build (c. EUR 3m in 2023 money).

[2][4] For several decades after its completion, it was the longest rail tunnel in Finland.
