• When driving the crossover, slow down, stay alert, exercise caution and watch for crews.
• Expect a significant grade change in the area; please pay extra attention when driving.
• Stay the course, but plan a little extra time to get to your destination.
• Do not speed in work zones; obey the posted speed limits.
• 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.

The following safety measures have been implemented on the project:

• Reduced speed limit to 60 mph, and installed Portable Variable Speed Limit Signs. These boards allow the project to adjust the speed limits in real-time based on weather conditions, crashes, or construction-related impacts. With this technology, crews can slow down traffic ahead of a crash, incident or weather impact, possibly reducing the likelihood of secondary crashes.
• Increased law enforcement by the Colorado State Patrol to cover the project seven days a week, contingent upon CSP resources.
• Ensure adequate first responder access by providing access breaks in the barrier where possible.
• Provide shoulder pull-off locations for emergencies.
• Limit lane closures to off-peak travel periods at night unless emergency situations warrant a lane closure such as road damage repairs or other emergency situations.
• No detouring traffic to alternate routes, such as CO 83 or CO 105.
• Dedicated multiple courtesy patrol vehicles to the project, which has helped greatly to get disabled vehicles off the road and traffic moving.
• Monitor traffic through a project operations center that uses cameras, signs and vehicle detection devices to help with incident management. 
• Deployed numerous Smart Work Zone systems and devices that warn motorists of backed up traffic, trucks entering and exiting the work zone and other incidents and activities.
• Stage equipment by the contractor prior to large snow events to assist with snow operations and response issues.
• Hold biweekly meetings with emergency response agency partners to coordinate efforts on project operations and work zone safety.
• Implemented significant safety improvements on the frontage roads from Larkspur to Castle Rock.
• Implemented extensive public relations efforts including, text alerts, social media, special media briefing events, paid advertising campaigns, public meetings, weekly e-blasts to stakeholders, regular meetings with stakeholders and elected officials, coordinating seamlessly between two counties.
• Added Bustang routes and ride-sharing program from Colorado Springs to the Denver Tech Center to give motorists other travel options during construction.
• Provide extra lane for the Renaissance Festival to help alleviate traffic congestion during this eight-week event.
