The overpass is one of the trickiest parts of the Southwest Parkway, a planned toll road that will stretch from the west side of downtown Fort Worth into Johnson County. The bridge requires numerous footings in the rail yard, but the railroad objected to any construction activities that would disrupt its traffic.
Negotiations over the $95-million overpass dragged on for months and ended only when the city agreed to build a temporary hump lead in the yard to help sort rail cars during bridge construction. The preliminary agreement was signed in January but was delayed until this month as both sides worked out details and Union Pacific tested the hump lead.
The parkway is a joint venture of the city, the Texas Department of Transportation and the North Texas Tollway Authority. The three groups are still negotiating a way to fund construction of the road's main lanes.
