Blasts crumble piers for old turnpike bridge over Kansas River

The last pieces of piers that shouldered loads for the Kansas Turnpike’s original Kansas River bridges were blasted with explosives about 2:15 p.m. today.

Rex Fleming, project engineer, deemed the demolition work a success.

"Everything is good and back to normal," Fleming said.

The tops of two concrete piers already had been removed. What’s left — stretching 22 feet underwater and into the riverbed below — was turned to rubble with specially designed charges.

The rubble was expected to settle on the river bottom, to be removed later by excavators.

Crews already are pouring piers for a new Kansas River bridge, one that’s being constructed alongside another span that opened last year. The work is part of a $130 million project to replace the 1950s-era bridges, overhaul interchanges and make other turnpike improvements.

Beginning Monday, the turnpike plans to close its East Lawrence interchange — that’s Exit 204, in North Lawrence — for seven months for reconstruction.
