The Benefits of Collaboration: Lincoln Avenue in Lone Tree A common misconception surrounding concrete paving is that it is time consuming and inconvenient for commuters and complicated for cities and counties to manage. Earlier this year Castle Rock Con- struction Company (CRCC), a CO/WY ACPA contractor member, proposed a solution to the City of Lone Tree, CO to greatly minimize the impacts of repairing 30+ year old concrete pavement that has surpassed its original design life and will continue to carry traffic. Lone Tree was looking to replace approximately 3,600 square yards of concrete pavement on Lincoln Avenue, a six-lane arterial road connecting two major routes (I-25 and South Parker Road) that is a thoroughfare for local drivers and commuters alike. The city initially planned for the construction to take eight weekend closures on this stretch of road, and worried about disruption to traffic and impact on the surrounding businesses. Castle Rock Construction Company proposed a plan to complete the entire project, including removing and replacing all panels in just one weekend, beginning work on Friday at 6:00pm and ending on the following Monday at 8:00am. The City of Lone Tree accepted that timeline and work began swiftly. On Friday April 6, 2018, CRCC began removing pavement and preparing the site, and paving began on Saturday morning. CRCC used two crews to complete the expedited project on the westbound side of Lincoln Ave. Ultimately CRCC removed 8 inches of concrete pavement and replaced it with 10 inches of concrete using Douglas County design and construc- tion standards along with CDOT specifications. Lone Tree permitted joint sealing to be completed the following week under minimal lane closures to allow for final completion of the work. This project was completed on time with construction ending by 6:00am on Monday, April 9th, cutting seven weeks of construction time off the city’s initial plan. Lisa A. Albers, P.E., City of Lone Tree Public Works & Capital Projects Manager, had this to say about the completion of the project, “Thanks to the well-orchestrated work by Castle Rock Construction Company, they were able to remove and re- place approximately 4,000 square yards of concrete within a 48-hour period in the westbound lanes of Lincoln Avenue from Peoria Street to Interstate 25. Their herculean efforts reduced our project schedule of eight weekends of lane closures down to one weekend.” The Lincoln Avenue project is a prime example of the efficient work that can be completed when contractors and local agencies collaborate.
