Construction Projects

Trust, accountability, and transparency.

With more than 40 infrastructure projects either completed, in progress or scheduled to break ground in 2019-2020, the City of Evans has launched "The Road Ahead" infrastructure campaign to help residents track and understand the major improvement efforts throughout the City of Evans.

The campaign is easily recognized by its maize and blue logo and will serve as an indicator of progress throughout the city. When a project is complete, a check will be placed on the logo.

37th STREET EXPANSION PROJECT PHASE 2A


Beginning on April 29, 2024, Evans will start construction on the next phase of the 37th Street widening project. The construction will extend from Sienna Avenue on the west to Stampede Drive on the east and transitioning back to the existing roadway east of Stampede Drive. Atmos Energy will also be working in the project area, relocating some existing gas lines to accommodate the road widening at the start of the project, this will result in full closure of the road while this work is on-going. The detour route will send drivers to US 34 on the north or 49th Street on the south. Our plan is to open the road after Atmos Energy completes their work.

Construction is expected to last through September so we ask your patience when driving in the cone zone. The plan is to keep the road open to two-way traffic for as much of the project duration as possible. Please use alternate routes when possible.

2024 ASPHALT SURFACE TREATMENT PROJECT - Work for the 2024 Asphalt Surface Treatment Project consists of 3/8” chip seal application on multiple local streets throughout the City of Evans. Locations are divided by Subdivisions and are prioritized for installation. All utility collars, and pavement marking symbols shall be protected with tar paper. The paper and tape must be removed once the product is distributed and sealed. There are thermoplastic “Stop Bars” that also require protection at the ends of all roads. There is no striping on any of the roadways to protect or to restripe. Surface Treatment Vicinity Maps

Work for Project # 1 (15th Avenue) of the 2024 Asphalt Reconstruction Project consists of roto-milling the entire surface of existing asphalt pavement estimated to be four (4) inches in depth, removal of (6”) six inches of in-situ sub-grade material, scarification, compaction and grading of earthen in-situ sub-grade material, installing a (6”) six inch Class 6 base course layer (crushed concrete is not a suitable replacement product and will be strictly refused), compaction and grading of base course layer, soil sterilization of entire surface of the base course layer, placement of a (2”) two inch bottom lift hot mix asphalt Grading S, SP 64-22, installing an emulsified tack layer, placement of a (2”) two inch top lift hot mix asphalt Grading S, SP 64-22, adjusting of existing water valves, sanitary sewer manholes, and storm drain manholes which are to be ¼” inch below the asphalt surface.  Concrete collars will not be installed around existing utility box structures and manholes, instead the existing concrete collars will be removed, and the utilities will be raised to grade prior to paving and asphalt will surround the utility boxes and manholes, installing (2’) two-foot-wide thermoplastic stop bars at stop sign intersections as dictated.

The City of Evans recognizes that the project is located on a local collector street with accessibility concerns for the residents during construction. There are (31) thirty-one single family homes that encompass the project. This site is also near a school, so summer construction is necessary.

Geotextile Grid is included in the contract in the event unstable sub-grade material is encountered. All QC Quality Control testing is to be considered inclusive of costs for compaction of each respective layer of street section whether it is asphalt, base material, fly-ash or earthen in nature. Traffic Control is broken out as a separate line item and not included in the mobilization costs.

EVANS STREET LIGHT INSTALLATION PROJECT

This project is intended light up areas of Evans that do not have adequate street lighting using funds from a grant that Evans has received from Colorado Department of Public Safety Division of Criminal Justice. The grant funds will be used to design, procure and install streetlights in vicinity of Highway 85 in areas with limited street lighting to improve safety in these neighborhoods. To provide complete design, installation, and purchasing of materials to install 58 Evans style local ornamental streetlights within (3) Three identified zones of service and one add alternate zone of service (4) with an additional 10 Evans style local ornamental streetlights for a possible total of 68 streetlights. Each lighting zone would be individually metered and would become the sole property of the City of Evans Lighting District. The city would also like a fourth zone to be designed that would continue along the frontage roads along the west side of US 85 to the city limits ending at the South Platte River. See attached Vicinity Maps. Installation of the streetlights in Zone 4 will be dependent if there are sufficient funds to complete Add Alternate # 1 in its entirety.

2024 EVO RADAR INSTALLATION PROJECT

Work for the 2024 EVO Radar Sensor Project will consist of installation  of eight  (8) Econolight EVO Radar Sensors at all City of Evans Traffic Signals except 37th Street and 65th Avenue. The intersections for installation are 37“ Street and 11th Avenue, 32nd Street and 11th Avenue,  37th Street and 17th Avenue, 37th Street and 23trd Avenue, 32nd Street and 23“' Avenue, 37th Street  and 29" Avenue, 37th Street and 35th Avenue, and 34th Street and 34th Avenue.

Installation will require the removal of all existing ITS Plus Cameras, wiring, and video card components from the intersections. Capping of open holes on the existing mast arms is a requirement. New holes will need to be drilled /cored through Evo (2) poles at each intersection at each radar location. Econolight will supply a representative to guide the contractor with the best location and height for each radar mount. Once all wire is removed and conduits are clear, the existing conduit is expected to be used to rewire the new EVO Radar systems. New wire may be pulled through the conduit using the old wire as a fish tape to pull through). All components for the Radar system  (Brackets, Radar Hub, and Radars) are already purchased for the new installations. Radar Hubs will be mounted in the traffic signal cabinet and will be connected to the existing Econolight Cobalt Controllers. The Econolight representative will assist and guide the contractor to program the new radar units. The City of Evans will also have our Traffic Engineer available to answer any questions that may arise.

It is anticipated that the traffic signals will be in flash mode while installation is in progress. Limited lane closures at the inside right turn lanes will he required at the poles selected to house the new radars, as well as center lane closures to access and remove the existing cameras and to cap the openings. Once the new system is installed, wired, and programmed the final removal of the ITS Plus video cards can be removed and the new system activated. A short blackout period may be experienced at this time. Flagging may be necessary for a short window of time at each intersection. EVO Radar Installation Project Map
