Stockholm is expanding its regional power grid. One new element is the 14-kilometer-long Anneberg-Skanstull Tunnel. HOCHTIEF is the technical leader of a joint venture, building this connecting link at depths between 50 and 100 meters. The project will be completed in 2024.
In a joint venture with Implenia, HOCHTIEF is building a major component of the new suburban railroad route in central Munich: the Marienhof central station (above). The station is located 40 meters underground, because the route will pass under two existing subway lines.

The project will improve environmental protection and the transportation infrastructure in San Diego County, California. The Flatiron-led joint venture includes adding carpool lanes to the I-5 highway, rail improvements, and replacing the bridge across the San Elijo Lagoon.
