The second Santiago Calatrava designed bridge in the Dallas skyline is about halfway complete.

One arch of the $111-million Margaret McDermott Bridge was completed last year, and the eastbound roadway will be finished in a few months. Work on the twin arch, composed of 39 steel segments, started in December.

The bridge, which is replacing an expanse of Interstate 30, will have pedestrian walkways and bike lanes on both sides. They will be accessible from the Coombs Creek Trail on the Oak Cliff side and at Riverfront Boulevard on the Dallas side.

The nonprofit Trinity Trust is contributing $1.1 million to cover a budget shortfall. The bridge otherwise is being paid for with federal funds ($91 million), regional transportation funds ($11.6 million), private donations ($6.3 millions) and city bond funds for public art ($1.9 million).

The city will be responsible for maintenance on the pedestrian paths and bikeways only, and the Texas Department of Transportation will pay for maintenance on the rest of the bridge.

It opens in summer 2017, when the $798 million Horseshoe Project is completed.
