Town to implement new traffic technology along Plum Creek Parkway in November, open house Oct. 19

Helping you get where you’re going is a priority for Castle Rock Public Works. Innovative technology is coming to the Plum Creek Parkway corridor to do just that.

As part of the road improvements along Plum Creek Parkway, the Town is installing a new electronic traffic management system. It sounds complicated, but it’s simple to use and is expected to smooth out the weekday commute for drivers getting to Interstate 25 during the morning rush hour.

Here’s how it will work:
New electronic signs will be installed along westbound Plum Creek Parkway. These electronic signs will designate lane assignments (whether they are through, through-or-right, or right-only), based on time of day.

Throughout most of the day, the signs will display arrows with the same lane assignments drivers are already used to. (The far right lane has access to northbound I-25, or goes through to the other side of the interstate. The middle lane only goes through.)

During the morning peak – roughly 4 a.m. to 9 a.m. – the lane assignments will change slightly so an extra lane of traffic can access northbound I-25. The far right lane will become a “right-turn-only” lane for drivers accessing I-25. The middle lane will become a “through-or-right” lane for additional access to the highway. A similar system will be set up along northbound Wilcox Street on the signal arms at Plum Creek Parkway, so the lane assignments match for those turning left onto Plum Creek Parkway.

Explore this new technology during an open house from 6-8 p.m. Wednesday, Oct. 19, at Town Hall, 100 N. Wilcox St.

“The new technology will allow drivers to use both lanes of Plum Creek Parkway in the morning peak to access I-25 north, rather than lining up single file in the right lane,” said Castle Rock Public Works Director Bob Goebel. “It’s our priority to improve traffic flow while being prudent with public funds. This approach is less costly than constructing an entirely new access lane and bridge widening, and provides a balanced use of existing infrastructure.”

Drivers should always pay attention on the road, but the Town is asking drivers to be extra alert as this change is made, which is expected in November. The system will be extensively tested before it is implemented. Watch the Town’s Facebook page,, for updates as we get closer to implementation.
