Cone Zone: Week Of June 5, 2023


The projects listed in this section are being managed by County Public Works staff through contractors. For more information, email, call 505.662.8150, or visit the “Projects/Public Works” link at Please slow down and use caution within the construction work zones.

Please note the below information is based on a schedule provided by the contractors and may change due to weather or other delays.

Let’s work together!

Have you seen the new message board and signage Public Works installed near the N.M. 502  roundabout? The signs are to encourage eastbound drivers in the right lane to continue to the “merge point” just west of the Crossroads Bible Church driveway, where drivers in both lanes should alternate in “zipper” fashion into the single lane. The “zipper method” is a proven process to help alleviate traffic congestion in similar circumstances.

Another proven way to help ease traffic congestion is by carpooling. Whether commuting locally or regionally, getting kids to and from practice, or simply heading out for the evening, carpooling is an excellent way to help minimize traffic, lower your gas costs, and positively impact the parking needs at your destination.

Share a ride with your spouse or friends. Take turns driving with coworkers or classmates. Join a carpool group, and grow your friendships with coworkers, instead of your wait in traffic! Headed to the Friday night concert? Carpool with others you know are going.

If the community works together to minimize traffic congestion, everyone’s commute will move a little smoother.
