TKDA met safety needs at a new rail station with a pedestrian tunnel
To provide a safe crossing at the proposed Fridley Station along the Northstar Commuter Rail, BNSF Railway Company needed to construct a pedestrian tunnel under five active tracks. TKDA was commissioned to prepare the bidding documents and oversee construction of the new tunnel.
The 160-foot long tunnel is 12 feet wide by 10 feet high and composed of 5-foot long, reinforced, precast, rectangular concrete segments. TKDA completed the project in two phases with short work windows. BNSF allowed a 2-day work window for the first phase of work and a 30-hour work window for the second phase of work.
