Munich motorists will from this month be able to speed along one of the city's busiest roads without disturbing local residents, thanks to the construction of a new glass insulation tunnel. German contractor Loharlens Engineering has constructed a new 280m long $7.5M glass tunnel to insulate nearby buildings from highway noise.

Glass panels supplied by UK manufacturer Vetrotech SaintGobain are designed to withstand fire in the tunnel, as well as cope with weather induced surface temperatures ranging from -35infinityC to +60 degree C.
