Construction workers are putting the finishing touches on an
extension of Ridgegate Parkway that provides another connection
between Lone Tree and Parker.
The $8-million project is expected to divert thousands of
vehicles off of Lincoln Avenue the day it opens. Officials from
Douglas County and Lone Tree initially planned on completing the
extension several years down the road, but intergovernmental
cooperation and a drop in the cost of construction has Ridgegate
Parkway opening the morning of Dec. 13.
Those who made the much-needed, 3.5-mile connection happen will
attend a ribbon-cutting at 9 a.m. where Ridgegate Parkway meets
South Peoria Street just east of Interstate 25.
Douglas County, which contributed $5 million to the project, is
clearly excited about the improvement of traffic flow in the
northern tier, calling Ridgegate Parkway a “mutually beneficial
addition to the county’s transportation infrastructure that
relieves traffic congestion on Lincoln Avenue between I-25 and
Parker Road and provides economic development stimulus to the
The road runs through land owned by the Coventry Development
Corporation, which developed the initial stages of RidgeGate,
including Super Target and Sprouts Farmers Market near Lincoln
Avenue and RidgeGate Parkway.
The parkway becomes Yosemite Street north of Lincoln Avenue; it
will connect with the existing extension of East Mainstreet as it
John Cotten, director of Lone Tree Public Works, did not have
specific estimates, but said he expects a good flow of traffic on
RidgeGate Parkway on opening day.
“We’re interested to see ourselves,” he said, when asked for
projected vehicle counts.
Initial estimates put the number around 15,000 vehicle trips per
day. Sean Owens, a road engineer who oversaw the project for
Douglas County, was not immediately available for an updated
Traffic counts will continue to build as those who commute from
Elbert County and southern areas of Douglas County discover the
route. Lincoln Avenue carries as many as 60,000 vehicle trips per
day and becomes bogged down with traffic during morning and evening
The Lincoln Avenue interchange with I-25 will also benefit as
many drivers will begin using the Ridgegate Parkway interchange
instead. A team of consultants from Felsburg, Holt, Ullevig
projected that motorists will save approximately $2 million per
year in reduced public commute time with the opening of the
The City of Lone Tree managed the design and construction of
Ridgegate Parkway East between I-25 and Peoria Street, and Peoria
Street from Crescent Moon Parkway to Ridgegate Parkway to provide
additional access to Lincoln Avenue. The county managed the
construction of the extension of Ridgegate Parkway/East Mainstreet
between Peoria Street and Meridian Village Parkway.
Cotten credited the cooperative efforts of Lone Tree, Douglas
County, the Southeast Transportation Management Authority, SPIMED
and Coventry for the early completion of the road.
Douglas County Commissioner Jack Hilbert and Lone Tree Mayor Jim
Gunning, members of the Southeast Transportation Management
Authority, obtained a $2.5-million grant from the Southeast Project
Investment Metro District by detailing the potential benefits of
the road to the region. Douglas County also put up $2.5 million in
matching funds. Coventry will reimburse the county for the
remainder of the construction cost once development begins along
the Ridgegate Parkway corridor.
