When construction to add a third lane on a segment of westbound I-694 through Shoreview begins on Monday, drivers will encounter a set up that will force them to pick a lane and live with their choice.
The Minnesota Department of Transportation will split the two traffic lanes just before Rice Street. Motorists who choose the lane that veers right will have access to on and off ramps between Rice Street and Lexington Avenue. Drivers who pick the lane that veers left will have no ability to get off the freeway until reaching I-35W.
"Cattle chutes, that's what we are calling them, informally," said spokesman Kent Barnard.
Officially, the left lane is designated as the through lane and the right lane as the local access lane, said project supervisor Tom Krier.
Signs will direct motorists into the proper lanes, but indecisive motorists or those who opt for the faster-moving lane and attempt to scoot over at the last nanosecond could become a highway menace.
"If somebody makes a last-second move, we might have a crash," Barnard said. "We are very aware that could happen. We're telling drivers to make a decision" and stick with it.
Westbound I-694 traffic will be alerted to the traffic change approximately ¾ mile before they have to make a choice. Signs will alert them to stay in the left lane for through traffic (the chute) and stay to the right for local traffic with ramp access at Rice Street, Victoria Street and Lexington Avenue. There will be additional signs just after motorists drive beneath the northbound I-35E flyover bridge, Barnard said..
Northbound I-35E traffic going to westbound I-694 will not have a choice. Those motorists will be merged to the right and will have to use the local access (right) side of westbound I-694. "This is for safety reasons since it would be difficult to get them over to the left for the through lane and have to cross traffic coming west on I-694," Barnard said.
