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
Asphalt paving operations on Chalk Bluff Road are progressing as scheduled and are currently on track to conclude in early to mid October. The overall project is expected to be completed in mid to late November.
Motorists should continue to expect periodic daytime traffic impacts as work progresses. Traffic may be reduced to a single lane with alternating traffic directed by flaggers and, when necessary, a pilot car. In addition to paving operations, intermittent shoulder work will occur at various locations throughout the project limits.
While the new asphalt surface may make it feel easier to travel at higher speeds, the project remains an active construction zone with crews and equipment working throughout the corridor. Please obey posted speed limits and help us keep our workers safe by slowing down and using extra caution when traveling through the work zone.
We appreciate everyone's continued patience as we near project completion.
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.
