HAYS–Work starts Monday on a roundabout at the intersection of 32nd and 33rd streets, in Hays, and traffic on the heavily traveled Vine Street/US-183 highway will slow in a couple weeks as the four-lane corridor is narrowed to one-lane each direction.


Smoky Hill Construction LLC, Salina, the contractor on the project, will install temporary traffic control signals, basically poles and span wires, said Hays city project manager John Braun.


Those signals will ultimately control the flow of head-to-head traffic on one northbound and one southbound lane on Vine/US-183.


After the signals are up, Vine will be down to one through-lane each direction for about 12 weeks, until late November, said Braun, explaining the changes at a news briefing Tuesday in City Hall, 1507 Main.


The switch is part of the $13.2 million roundabout reconstruction of Vine Street where construction has been underway for a couple months to re-do the west frontage road and two side streets there in preparation.


Next week, while the temporary traffic signaling is going up, there will be two through-lanes in each direction, he said.


"We’re kind of easing into it," he said.


Once the temporary signals are in place and fully functional by the end of next week, Smoky Hill Construction will begin shifting southbound traffic on Vine to the east side, where traffic will be head-to-head one-lane in the northbound lanes through the 32nd and 33rd street intersection area.


"That will take probably about six weeks to build the west half of the roundabout," Braun said. "Then they’ll switch it over, and it will be one lane in each direction on the other side, on the new portion, while they’re building the east half. And that will be another six weeks. And by that time it will be November, and it will be finished for the year."
