Remember to Slow for the Cone Zone 

The following tips are to help you stay safe while traveling through maintenance and construction work zones.

  • Do not speed in work zones; obey the posted speed limits.
  • Stay Alert! Expect the unexpected.
  • Watch for workers; drive with caution.
  • Don't change lanes unnecessarily.
  • Avoid using mobile devices such as phones while driving in work zones.
  • Turn on headlights so that workers and other drivers can see you.
  • Be especially alert at night while driving in work zones.
  • Expect delays, especially during peak travel times.
  • Allow ample space between you and the car in front of you.
  • Anticipate lane shifts, and merge when directed to do so.
  • Be patient!

To ensure drivers – and our crews – get home safely, the I-25 South Gap project team is on the cutting edge of technology. Smart Work Zone technology will help increase safety and maintain traffic flow through this vital transportation corridor.

I-25 South Gap is the first project in the state to implement all of the following Smart Work Zone technology:

Queue warning system

As a vital transportation corridor for commuting and commerce, it’s important to keep motorists apprised of delays so they know what to expect and can take alternate routes as needed. With this technology, sensors detect speeds upstream, which update the variable message signs to let motorists know the estimated time it will take to get to certain locations such as Larkspur, Monument, etc.

Pan tilt zoom cameras

Additional portable cameras have been installed to capture areas along the corridor that CDOT cameras currently don’t have access to. These cameras feed into the Onsite Project Traffic Operations Center to help the project team see traffic in real-time.

Truck warning system

With an average of three trucks every five minutes delivering and/or picking up material daily throughout the 18-mile work zone, the I-25 South Gap project team wants to warn drivers about trucks entering/exiting the highway. To do so, a sensor is attached to a portable sign in the work zone. When a construction truck passes the sensor, a variable message board (pictured to the right) farther back in the corridor is triggered and will light up a sign to warn motorists in time to slow down and yield to the truck.

Portable Variable Speed Limit Sighs

The project will soon have the ability to change the speed limits in real-time – based on weather conditions, crashes or construction-related impacts. Those enforceable speed limits will be displayed on 22 variable speed limit signs that will soon be installed along northbound and southbound I-25 from Monument to Castle Rock. The variable signs will replace existing static speed limit signs.

Onsite Project Traffic Operations Center

This is the first-ever project in Colorado to have an onsite Traffic Operations Center to monitor current roadway conditions and possibly reduce congestion by suggesting alternate routes to drivers when incidents occur. Typically, construction projects feed into the larger TOCs across the state. Having a TOC onsite benefits both motorists and the project team because the TOC can gather and provide real-time information.

The project team also coordinates bi-weekly with emergency service providers, and funds increased patrolling through the corridor to encourage motorists to adhere to posted speed limits. The project also has a dedicated Courtesy Patrol vehicle to help stalled or crashed vehicles get safely off the road -- and to keep traffic moving.
