MESQUITE, Nev. -- Road construction crews are set to slide a new bridge assembly into place on Interstate 15 in Nevada using no-slip rails, hydraulic jacks and liquid dish soap for lubrication.
Similar "bridge slide" operations have been done in other places, but state Department of Transportation spokeswoman Michelle Booth says the Tuesday night operation in Mesquite will be a first for Nevada.
It's expected to start sometime after 7 p.m. and take about four hours.
Booth says motorists between Salt Lake City and Las Vegas should be driving on the new structures by Wednesday night.
The interstate won't close. I-15 traffic is diverted around the work site on temporary bypass roads.

Oh, and what kind of dish soap?
Dawn, she said.
