The Kansas Turnpike is postponing plans for blasting another section of original Kansas River bridge at the northern edge of Lawrence.

Crews now intend to detonate explosives on the turnpike’s former eastbound bridge at 10 a.m. Wednesday, a day later than previously scheduled.

Turns out preparations are taking a bit longer than expected, and weather forecasts call for ice and snow Monday night into Tuesday.

“There’s no reason to push it,” said Rex Fleming, the turnpike’s project engineer on the job.

The blast is set to be larger and more dramatic than two earlier blasts, part of ongoing demolition of old bridges that had been in service for more than 50 years.

Another blast — for much of the former westbound bridge — is set for 10 a.m. Dec. 15.
