Chalk Bluff Road Improvements
Laramie County, in partnership with contractor Connell Resources Inc., will begin a major road improvement project on Chalk Bluff Road in late April. The project will begin at the intersection of Chalk Bluff Road and US Highway 85, just south of Cheyenne, and extend approximately nine miles east along Chalk Bluff Road toward the community of Carpenter.
The project includes rebuilding and widening approximately nine miles of roadway as part of the county’s ongoing efforts to enhance transportation infrastructure and support responsible growth. As the region continues to expand, improvements to key corridors like Chalk Bluff Road help keep communities connected and support local economic activity.
Construction will provide several benefits to the community, including smoother pavement, wider travel lanes and improved overall safety. These upgrades are designed to reduce crash risk, particularly in areas that are currently narrow or deteriorating. The improved roadway will also better accommodate larger vehicles, such as farm equipment and service trucks, making travel safer and more efficient for all users.
Construction is anticipated to be completed in November 2026.

Work Schedule
Traffic Impacts
Concrete Treated Subbase (CTS) work begins on July 13 along Chalk Bluff Road. This work includes treating the roadway's structural base to improve its condition, extend its service life, and provide a smoother driving surface.
To safely accommodate construction activities, temporary traffic signals will direct motorists through the work zone. Traffic will be reduced to a single lane with alternating directions controlled by the signals. The temporary signals will operate day and night throughout the CTS work and are expected to remain in place until early August. During this time, there will be no centerline striping, so drivers should pay close attention to all traffic control devices and be prepared to stop when directed.
Residents and motorists are urged to use extra caution, particularly during nighttime travel. If you encounter an oncoming vehicle on a narrow section of roadway, use your discretion to safely pull off to the side of the road, when possible, to allow traffic to pass.
Please reduce your speed, remain alert and watch for construction crews and equipment throughout the work zone.
We appreciate your patience as these improvements are completed.
Flagging Operations
-
Traffic will be reduced to one lane.
-
Flaggers will direct motorists through the work zone.
-
Drivers should be prepared to stop and proceed when instructed.
-
Short delays are expected.
Pilot Car Operations
-
Motorists will be guided through the work zone by a pilot car.
-
Vehicles will travel in a controlled group (convoy).
-
Delays may be slightly longer but more predictable.
Mailbox Relocation
As road construction progresses, mailboxes may need to be temporarily relocated from time to time to accommodate the work. Mailboxes may be moved up to 100 feet from their normal location, and access will be maintained throughout the project.
We are in regular communication with the mail carrier, who has been informed of these temporary mailbox relocations to help ensure uninterrupted mail delivery.
We apologize for any inconvenience this may cause and appreciate your patience and cooperation as we work to improve the roadway.
Mailbox Transition to Cluster Box Units (CBUs)
As part of USPS delivery service requirements, the existing individual mailboxes in the project area will be transitioned to centralized mail delivery through Cluster Box Units (CBUs). Residents will receive their mail from the designated CBU location assigned by USPS.
USPS Centralized Mail Delivery (POM 631.2)
Under USPS Postal Operations Manual (POM) Section 631.2, centralized delivery is the preferred method of mail service. Centralized delivery may be provided through Cluster Box Units (CBUs), horizontal locked mail receptacles, wall-mounted receptacles, call windows, or other USPS-approved centralized systems. USPS determines the appropriate delivery method for an area and may require customers to receive mail at a designated centralized mailbox location.
