Project Status as of November 2013: The project is currently inactive. The Corridor Study was completed in late 2012 and information posted to the web site. Project Segment A ( I-25 to Lake Woodmoor Drive) has been approved for federal funding and will move forward into preliminary design once the required matching County funds are available for this project. County funds are not currently available. The remainder of the project improvements (from Lake Woodmoor Drive to SH 83) are not currently funded, but are included in the reauthorization of the voter approved PPRTA Capital funding program, which will kick off in 2015 and extend to 2025. Further design work on these improvements are not expected to commence until 2015 at the earliest. We will update this information as the project status changes.
Highway 105 Corridor Location
El Paso County is conducting a Corridor Study for Highway 105 between Interstate 25 (I-25) and SH 83, a distance of about 5 miles. This section of roadway provides direct access to I-25 and connects the eastern portion of El Paso County and Palmer Lake. The study is being conducted to identify capacity, mobility and safety improvements as well as a plan for implementing those improvements based on need and available funding. While a long term plan will be developed, it is anticipated that the improvements will be phased in over the course of several years. Safety improvements will be completed first, with capacity improvements to be completed only as conditions warrant and funding becomes available. This study will prioritize improvements for design and construction as well as identify any operational changes that could help maximize efficiency in the interim. Systemwide design features such as drainage will be investigated to determine the long term solution. Local and regional plans have previously identified the need for this section of Highway 105 to be upgraded; and this study will be coordinated with concurrent efforts. The study will include opportunity for stakeholder review and comment and will ultimately be documented in the Corridor Plan that will set the direction for improvements in the corridor.
Purpose and Need
The purpose of the study and analysis is to address the problem of congestion and safety between I-25 and SH 83; conditions which will continue to worsen as development and population growth continue in the area. The Highway 105 Corridor Study will examine the entire stretch of roadway to develop a plan to address corridor-wide and site specific issues while minimizing impacts to the surrounding natural and human environment. A planning horizon of 2040 will be used to evaluate both existing and future conditions. The result will be a Corridor Plan that identifies the specific improvements needed to address existing and future corridor operational deficiencies, as well as the appropriate timing and phasing for the improvements. Both access management and geometric improvements will be considered as a means to optimize corridor traffic operations and improve the capacity of Highway 105, while balancing access needs to adjacent areas.
Currently in the Corridor there are inconsistent shoulder widths and limited sight distance in some areas due to horizontal or vertical curves. The crash pattern in the Corridor coincides with areas of substandard geometric design as well as a high number of crashes at the I-25 ramps which is expected due to higher volumes. A large number of the crashes are rear-end collisions, which supports the connection between substandard design and the event. There are numerous access points along Highway 105 for commercial, residential, and public use that will be examined and for which a consistent access plan will be developed.
Drainage is a concern through the Corridor. Currently there is a curb and gutter system in the western portion of the study area that ends in the vicinity of Monument Academy. To the east, storm water simply runs off the road into a system of culverts and roadside ditches, many of which suffer erosion and sediment build-up. Drainage, including impacts to receiving waters and adjacent wetlands, will be studied and incorporated as appropriate in the project improvements. Wetlands and sensitive habitats will be mapped and avoided to the extent possible. Any unavoidable impacts will be first minimized and then mitigated in coordination with the jurisdictional agency (i.e., US Fish and Wildlife Service or US Army Corps of Engineers).
Frequently Asked Questions about the Highway 105 Corridor Study
- Highway 105 Operations Analysis
Near-term funding has not been identified for construction improvements to this stretch of Highway 105. The study will examine possibilities for short term, less costly changes including access management and interim intersection improvements that may be implemented to help address existing mobility and safety issues. The Plan will outline both short term and long term improvements that should be implemented in the Corridor.
- Highway 105 and Adjacent Street Intersection
A number of intersections have poor sight distance due to either vertical or horizontal curves. Additionally, shoulders are narrow and in some places non-existent. This results in both mobility and safety concerns for all travelers, whether in vehicles, on foot, or bicycles.
- Multi-modal Options
Transit needs in the study area will be coordinated with Mountain Metro Transit and will focus on the existing park and ride at the northeast corner of Highway 105 and I-25. Potential enhancements for the safety of pedestrians and bicyclists will be evaluated and incorporated as appropriate in the corridor.
- Screening Process
Improvement options will be "screened" to create those that best meet the needs of the corridor in relation to transportation while avoiding and minimizing natural and human environmental impacts. This will include consideration of impacts to wetlands, floodplains, noise and access as well as cost-effectiveness.
- Public Information Process
Throughout the course of the study, the project team will actively engage the public and stakeholders to identify a balanced "solution" for the corridor. This will include local and regional agencies.
