Stolfus is assisted CDOT Region 4 to deploy and evaluate an adaptive traffic signal system along SH 119 near Longmont, Colorado. The adaptive system encompasses a total of eight signals, including the I-25 / SH 119 ramp terminals. In addition to providing Systems Engineering Analysis (SEA) and signal design services for the project, Stolfus and All Traffic Data conducted a comprehensive data collection program to evaluate before/after conditions as well as the effectiveness of an adaptive traffic signal system during construction (the corridor was reconstructed and traffic was in a head-to-head configuration on one side of the divided highway during construction). Design of the project was completed in 2015 and the adaptive signal system has been deployed. Stolfus is currently preparing an evaluation of the adaptive system.
In 2014, the LiveWell Huerfano County Bike and Pedestrian Advocacy Team presented findings/recommendations to CDOT, the City of Walsenburg, and Huerfano County regarding potential improvements within the City of Walsenburg that would support increased bicycle and pedestrian activity within the city. Specific challenges for pedestrians and bicycles crossing I-25C (Main Street/Walsen Avenue) and US 160 (7th Street), as well as continuity of routes along these two corridors were identified. Spurred on by the presentation, CDOT was able to obtain funding in 2015 for a pedestrian/bicycle study and an initial construction project.
Stolfus helped CDOT partner with the City, County and LiveWell to develop, evaluate and prioritize pedestrian and bicycle improvements along the State Highway routes in the city. Safe crossing locations for access to community amenities, improved sidewalk connections and ADA accessibility along the highway and at existing pinch points, improved routes to schools, and opportunities for on-street bicycle lanes were evaluated as part of the study. Opportunities to reassign space within existing right-of-way to accommodate and balance all transportation modes were pursued where feasible.
In January, 2016 the project team engaged the local community in the process. Close to fifty people attended a public meeting held to present project goals, benefits, and alternatives and seek public input. Overall, the community feedback was positive, especially related to improved crossings and sidewalk connections. With local feedback in hand, alternatives were evaluated and prioritized based on a set of criteria established at the beginning of the project. CDOT has released a new task order to Stolfus to design improvements at up to three locations in the study, including the following:
- Improved crossings with rectangular rapid flashing beacons (RRFB’s) at the library and City Park pool
- Sidewalk connectivity between the library and the high school on Pine Street. Adding a shared use path across an existing box culvert in this segment will provide safe facilities for pedestrians and cyclists who currently are forced to share vehicular lanes in order to cross the structure.
Construction is currently planned for Summer 2017.
In 2015, CDOT Region 3 released a task order to Stolfus, under our General Engineering NPS contract, to design and provide construction documents for resurfacing and ADA ramp upgrades on approximately 4 miles of US 24 in Minturn. During that design, Stolfus also was awarded a contract by the Town of Minturn to design the US 24 Pedestrian/Bicycle Improvements project through an overlapping portion of the same corridor. The corridor serves many transportation modes, including pedestrians (with school routes), bicycles, commercial trucks and passenger vehicles. There is an inconsistent cross-section of curb, gutter, sidewalk, pavement width, and storm drainage facilities. This inconsistency creates many unsafe situations for all modes of transportation. Stolfus studied the corridor and developed and facilitated multiple planning and public Open House meetings with the Town, CDOT, and other stakeholders. Following the studies and meetings, Town Council approved design and construction of improvements to two planned segments. The design looks to maintain some existing downtown parking while adding curb, gutter, and sidewalk and routing storm runoff away from private property and to a storm sewer system. Stolfus also developed the Transportation Alternative Program (TAP) grant application for the Town. In October 2016, the Town was awarded the entire TAP grant request for this project.
Elizabeth Stolfus recently graced the Winter 2017 cover of ACEC’s Engineering Colorado magazine with some of her first-responder partners. Check out the article and her President’s View column here.
Stolfus recently attended the FHWA’s Localized Bottleneck Reduction Program Summit in Lakewood, CO. The FHWA’s Localized Bottleneck Reduction (LBR) Program supports outreach to transportation professionals on how to incorporate low-cost, quick turnaround solutions to “chokepoint” problems. The summit was an overview of the national perspective, successful case studies of sample projects, and case study programs from other states. CDOT representatives also provided an overview of where Colorado is today and where we are headed. There was also a segment devoted to recent innovative alternative solutions, such as Continuous Flow Intersections (CFIs), Displaced Left Turn (DLT) intersections, and Diverging Diamond Interchanges.
Currently, Stolfus is participating in CDOT’s COBRA (Colorado Bottleneck Reduction Assessment) program by providing assessments at various locations as part of our NPS Traffic Engineering contract.
No foolin’! On Friday, April 1st, Gabriella Arismendi, a Transportation Planner at Stolfus, not only joined other Stolfus attendees, but also treated the Colorado Transportation Symposium to a presentation of the findings of the SR50 Bus Rapid Transit (BRT) Health Impact Assessment (HIA), a Florida based project.
HIAs are a data-driven, community based study to understand the positive and negative health impacts a program or policy might have on the community.
-Bicycle and pedestrian safety as a last mile connection to the transit line
-Economic redevelopment opportunities.
The study found that the BRT would have tremendous positive impacts, starting with economic redevelopment which in turn would improve bicycle and pedestrian infrastructure. By improving the land uses and infrastructure, corridor residents would feel comfortable using the transit line and hence increase their levels of physical activity. This transit line also increases residents’ access to educational facilities, grocery stores, and employment centers.
The study recommended construction of the BRT and for state and local governments to implement Complete Streets policies along the corridor.

Three of our senior managers attended this excellent seminar put on by the American Council of Engineering Companies (ACEC) in late March. It comes to Denver every few years so we like to send some folks when it’s here. The seminar included a good mix of topics for those engineers that are transitioning from managing projects and other people to managing a business. Topics included Leadership, Strategy, Growth Horizons, Change and Transition, Generations in the Workplace, Contracts and Risk Management, Finance, Business Ownership and Transition, and Marketing & Business Development. All of the speakers knew their material well and each brought a different style and perspective. In particular, Rod Hoffman of S&H Consulting, kept the group moving around, sharing ideas, and thinking; which led to opportunities to get to know one another and share similar experiences from diverse companies and locations.
Does your latest project include bike lanes? Have you planned or designed them on previous projects? Are you up to date on the latest guidelines? Whatever you current know-how is, we suggest you check out the FHWA Separated Bike Lane Planning and Design Guide.
In this book, David E. Goldberg and Mark Somerville share their story of the coming transformation of engineering education. The bestselling author of several books about the “changing workplace,” Daniel Pink, calls it, “(not) just a book about engineering. It’s a book about education, entrepreneurship, and – ultimately – the future.”
