Multi-Use Trail and Park Engineering

Adams County, Colorado
​Adams County Bridge 303

The RGA team designed an 80' single-span bridge, a quarter mile of roadway, channel improvements and a park. The roadway stayed open at all times during construction.
​

City of Alamosa, Colorado
​Alamosa Pedestrian Bridge

This project required the design of a 300' three-span bridge over the Rio Grande River. This bridge utilized precast box girders and a concrete deck. The abutments and piers were founded on steel piling to protect against river scour. RGA coordinated with the U.S. Army Corps for the 404 Permit and with their levee project in Alamosa. RGA provided construction observation and administration. 

City and County of Boulder, Colorado
U.S. 36 and Baseline Road Bikeway Connector

The RGA team provided the design of approximately 1,000 LF of a concrete bikeway connector along U.S. 36 and Baseline Road in conjunction with highway and ramp widening. Work included profiles, design of an underpass under the on-ramp to U.S. 36, extensive rock retaining walls, storm sewer and irrigation ditch bypass, local drainage and coordination with CDOT Region IV. 

City of Grand Junction, Colorado
​Colorado River Pedestrian Bridge

This three-span bridge is 410-feet long and utilizes two G68 pre-stressed girders (per span) and a 12-foot wide concrete deck. At each pier, there is a 6-foot radius observation platform on each side of the walkway. There are lights embedded in the rail posts that illuminate the deck without lighting up the entire river. There are single 54-inch diameter concrete caissons drilled to bedrock at each pier and 24-inch diameter caissons at the abutments. The RGA team received an ACI Award of Commendation for the design of this bridge.

City of Sheridan, Colorado
Schools Trail Connection System Project

RGA had the challenge of fitting the concrete trail to existing grades by S. Irving Street and the existing drainage gulley, large trees and Denver Water water mains at the W. Quincy Avenue ROW. This project consisted of the installation of approximately 2,500 linear feet of 10’ wide concrete trail, 140 linear feet of CMP and 95 linear feet of retaining wall as well as miscellaneous signing, railing and grading. Parts of the trail are within a small section of the City of Denver. The rest of the project was within the boundaries of the City of Sheridan. The trail improvements are along S. Irving Street between W. Quincy Avenue and W. Oxford Avenue and along W. Quincy between S. Irving Street and S. Federal Boulevard. This project provided off-street pedestrian and bike connection between Ora Oliver Elementary School, Sheridan High School, Sheridan Middle School and Alice Terry Elementary School, as well as Alice Terry Park and Sheridan City Park. This project also included coordination and approvals from the City and County of Denver and Fort Logan Officials.

City of Sheridan, Colorado
Safety Improvements to Bear Creek Trail Crossing at S. Lowell Boulevard

RGA assisted with the Arapahoe County Open Space planning grant application. With this grant, RGA assisted the City with improving the safety of the crossing of Bear Creek Trail with Lowell Boulevard.  This was achieved through the following infrastructure modifications: realignment of the Bear Creek Trail as it approaches S. Lowell Blvd. from the east; replacement of a portion of the existing 5’ raised sidewalk with an 8’ raised walk on the bridge to accommodate two-way bike and pedestrian traffic; realignment of the intersection of S. King St. and S. Lowell Blvd. which created a rest area with a bike repair station and bench; installation of a raised concrete crossing (speed hump) on S. Lowell Blvd.; installation of truncated domes at the west side of S. Lowell Blvd. and in 3 new curb ramps to meet ADA requirements; and installation of two crossing signs with pedestrian activated rectangular rapid flashing beacons.

City of Sheridan, Colorado
Bear Creek Trail Crossing at South Lowell Boulevard Feasibility Study

In the spring of 2015, the City of Sheridan was awarded an Arapahoe County Open Space Planning Grant to conduct a feasibility analysis of alternative crossings for the Bear Creek Trail intersection with South Lowell Boulevard. The trail in this area had a difficult, highly dangerous and circuitous crossing of South Lowell Boulevard. The City of Sheridan and RGA completed design surveys, geotechnical evaluation, and preliminary designs to determine alternatives to make this crossing safer. 

City of Thornton, Colorado
​​City-Wide Trail Improvements

The RGA team provided the design of over 14,000 LF of concrete and asphalt pedestrian and bike trails throughout the City.  Trails included creek-side bikeways, trails through parks and roadside bicycle lanes.  Work included profiles, grading, low water crossings, bridge crossings, hydraulic drop structures, local drainage, wetland analysis, and coordination with Urban Drainage and Flood Control District (UDFCD) and the City of Thornton.  The Niver Creek segment included a pedestrian bridge incorporated into the design of a storm water energy dissipater.

South Suburban Park & Recreation District, Centennial, Colorado
Dutch Creek Pedestrian Bridge

Previous to the design and construction of this bridge, the District bike path, along South Platte Canyon Road, crossed the concrete box culvert shown in the photograph.  When the Platte Canyon Road was to be widened, the bike path was relocated to the adjacent pedestrian bridge.  This is a 95 foot, single span bridge that supported on concrete spread footings. 

South Suburban Park & Recreation District, Centennial, Colorado
Orchard Pedestrian Bridge

RGA designed this 55-foot single-span bridge over the Highline Canal. This project also included the foundation design and modifications to the Highline Canal Trail, near the bridge.  The bridge allowed additional neighborhoods access to the extensive Highline Canal trail system.
