2026 Project Information

Each year, the City begins a refresh of neighborhood streets that helps extend the life of roadway infrastructure throughout Castle Pines. This effort, known as the Pavement Maintenance Program, is a strategic, proactive approach to extending the lifespan of roadways while minimizing the cost of maintaining road surfaces. 

The community is divided into regions to focus on each year, and using several software systems, staff analyzes which roads should be addressed and which repair method should be used.

Buffalo Trail Reconstruction

This year's program will include the complete reconstruction of Buffalo Trail between Monarch Boulevard and Twisted Oak Drive. This work is scheduled to begin the week of June 1, after the current school year ends, and be completed before school resumes in the fall to limit impacts.

Neighborhoods adjacent to the Buffalo Trail closure can use the neighborhood access routes indicated on the map (right) to access Monarch Boulevard. Non-local traffic should access Monarch Boulevard via Castle Pines Parkway.

Other Areas Identified for Improvement

The primary areas of focus for the 2026 program include neighborhoods in the western portions of the City.

Road Improvement Methods

Depending on road condition, there are several repair and maintenance options that can be used to extend the life of the roadway infrastructure. Check out the various methods below for more information about the different approaches.

Patching

When the entire area does not need to be replaced, patching is used to repair localized damage in asphalt surfaces. It is used below other surface treatments when the damage is deeper, and is a cost-effective way to fix specific issues and extend the life of the pavement.

Crack Sealing

When water infiltrates cracks, it can weaken the base and sub-base layers, leading to more severe pavement issues. Crack sealing is used to keep water and debris out of pavement cracks by filling these cracks with a hot, rubberized sealant to create a barrier against moisture. This preserves the structural integrity of the pavement.

Slurry Seal

A slurry seal is a cost-effective maintenance treatment for asphalt pavements, used to extend their lifespan by sealing cracks, restoring flexibility, and improving skid resistance. It's a mix of emulsified asphalt, water, fine aggregate, and additives that's applied to the existing pavement surface.

Mill and Overlay

Often done to remove irregularities, adjust the grade, or fix damage like ruts or cracks, this method removes the top layer of a paved surface to prepare it for resurfacing or repair. The milled asphalt can then be recycled and used in new paving projects.
