CEDAR PARK, Texas (KXAN) — Over the next few days, the intersection at Ranch to Market 1431 and Ronald Reagan Boulevard in Cedar Park will see some major changes in preparation for the opening of the county’s first continuous flow intersection.

Before the continuous flow intersection opens on Tuesday, Aug. 2, construction crews will have to implement the following closures:

Sunday, 8 p.m. to Monday, 6 a.m.: Various lane closures, eastbound pavement work Work on Sunday night includes blacking out all of the existing eastbound pavement markings, adjusting the traffic signals, and restriping the eastbound RM 1431 through lanes to the new lane assignments.

Monday, 8 p.m. to Tuesday, 6 a.m.: Westbound work, intersection closed, expect detours On Monday night, crews will black out all of the existing westbound and RM 1431/Parmer Lane intersection pavement markings, as well as adjust the traffic signals for the new westbound lanes. Beginning at 10 p.m., the RM 1431/Parmer Lane intersection will be closed to left-turning and through-traffic. All traffic will be forced to make a right turn and follow detours in order for work to take place in the middle of the intersection.

A continuous flow intersection, or CFI, allows left-turning traffic and through-traffic to move simultaneously.

“We know that driving through this new type of intersection is different, as it’s the first-of-its-kind in this area,” said Bobby Ramthun, TxDOT area engineer. “However, once you get used to it, you’ll find that it is not difficult to understand and navigate. If you follow the traffic signs and road stripes, it will guide you straight through the intersection.”See how a CFI works:
