Cost of Margaret McDermott Bridge increases by $12 million, but city to cover with private money, ‘value engineering’

At Thursday’s meeting of the Regional Transportation Council in Arlington, it was revealed that the so-called “signature elements” of the Margaret McDermott Bridge will cost about $12 million more than expected, increasing its price tag from around $102.6 million to $114.9 million. Turns out, it’s not cheap to dress up the new Interstate 30 bridge, much less make it hikeable and bikeable.
The city of Dallas says it will cover the cost overrun using private money, bond funds and “value engineering” intended to reduce the high price of remaking the so-called Horseshoe. Those figures are revealed in Monday’s Trinity River Corridor Project Council Committee meeting agenda: The Trinity Trust will kick in $5 million, while the Dallas Foundation will add $450,000 to the so-called IH30 Bridge Donation Fund into which private donations are deposited.
And the design is complete: Suhm says it will still feature two arches, each 1,125 feet long. She says they’ll be 286 feet high “from the deck of the bridge,” which is more or less three-quarters the height of the Margaret Hunt Hill Bridge’s arch.
“And that length means it goes almost all the way from one levee to the other,” says Suhm. “It’s a big arch.”
Alas, for now the plan is still to put a bicycle component on one side of the 15-lane bridge and the pedestrian component on the other.
“If we raise additional money in the spring, we’ll do both on both sides,” says Suhm. “But I can’t do that right now.”
