Douglas County Begins $13M Pine Drive Widening Project in Parker

Pine Drive in Parker becomes a full-scale construction corridor beginning the week of April 6 as Douglas County kicks off a $13,218,000 widening project that will eventually double the road's travel capacity between Inspiration Drive and Lincoln Avenue.

Hamon Infrastructure Co. is the general contractor on the job, with Douglas County Public Works overseeing construction through an anticipated finish in late July 2027, a roughly 16-month build.

The physical transformation is substantial. Pine Drive expands from two lanes to four, with two lanes running in each direction. New traffic signals go in at the Ponderosa Drive/Pine Drive and Pine Lane/Pine Drive intersections. Pine Lane gets a through lane added in each direction along with a center turn lane. A new westbound right-turn deceleration lane will be built at Dixon Drive/Pine Lane. Together, those changes target the queuing and crash exposure that has grown at peak-hour chokepoints as Parker has expanded.

Commuters should expect the corridor to feel noticeably different before it gets better. Early construction brings single-lane closures, flagging operations, traffic shifts, increased truck traffic and noise. Crews work Monday through Friday, 7 a.m. to 7 p.m.; Saturday hours require approval from the County Engineer and are not guaranteed.

A separate but overlapping disruption adds to the timeline: Xcel Energy is relocating gas lines along Pine Lane concurrently with road construction. That utility work creates its own alternating single-lane traffic controlled by flaggers, with potential delays of up to 10 minutes during certain work windows. Drivers approaching Pine Lane from Dixon Drive should plan extra buffer time during the combined phases.

The $13,218,000 price tag is entirely county-funded, with no state grants or developer contributions. Douglas County has placed the Pine Drive effort inside a broader 2026 capital program targeting growth pressure in Parker, Lone Tree and Castle Rock, an approach that prioritizes arterial upgrades now rather than deferring them.

Douglas County Public Works set up a project hotline at 719-749-7978 and a dedicated email at pinedrive.parker@gmail.com for schedule updates, construction notices and questions about the phasing. The county also posted a project map and milestone schedule online and said updates will follow as work progresses. Anyone experiencing an urgent issue related to active lane closures or flagging operations can reach the hotline directly during construction hours.
