A mobile bridge used for motorway maintenance on highways. ASTRA Bridge A1 in Switzerland, developed by the ASTRA. The Bridge allows resurfacing or repair work to be done on a motorway section without needing to close lanes or create traffic jams. It's a modular steel bridge that can be assembled and disassembled for easy transport. Traffic is diverted above the bridge on two lanes, while workers have access to a 100-meter space underneath the bridge for construction activities. - Minimizes traf
