Milchbuck Tunnel
From Wikipedia, the free encyclopedia
The Milchbuck Tunnel is a motorroad tunnel in Switzerland, and forms part of the A1L motorway from Zürich Schwamendingen to Zürich Letten.
The tunnel constructed in 1978 is 1.8 km long.
The southwestern end lies on Wasserwerk Street, which leads into central Zürich.
A proposed second tunnel hole (to create two separate tunnels for two directions of traffic) was turned down. Now, only one lane handles traffic into downtown Zurich, while two lanes handle traffic leaving the city.
By 2006, the emergency services in the tunnel will be upgraded, with the escape path being optimised.
