Welcome to CDOT's first web-based Statewide Transportation Plan. This plan is a vision document that outlines what our multimodal transportation options will look like in Colorado over the next 10 to 25 years. It is divided into four sections plus an executive summary, each of which helps to illustrate where Colorado stands today, the challenges that we face, and how we will continue to make progress in the future.

The Pan-American Highway, monument to a centurys worth of diplomacy and investment, education and engineering, scandal and sweat, is the longest road in the world, passable everywhere save the mythic Darien Gap that straddles Panama and Colombia. The highways history, however, has long remained a mystery, a story scattered among government archives, private papers, and fading memories. In contrast to the Panama Canal and its vast literature, the Pan-American...

This is a three-year planning document that will integrate safety planning efforts of all safety stakeholders into one document that serves as a tool for future planning efforts across the state.

This study determined the feasibility of using driven piles to stabilize highway embankment slopes. The activities performed under this study were a detailed literature review, a national survey of state DOTs, a review of inspection and stabilization mitigation reports, targeted field inspections, a cost comparison analysis, and a finite element study. The results of this study show that driven piles can be a cost-effective solution to stabilizing...

The objective of this project was to integrate the American Association of State Highway and Transportation Officials (AASHTO) Mechanistic-Empirical Pavement Design Guide, Interim Edition: A Manual of Practice and its accompanying software into the daily pavement design, evaluation, rehabilitation, management, and forensic analysis practices and operations of the Colorado Department of Transportation (CDOT).

This research project enables CDOT to answer the question of whether or not pedestrians and bicyclists are being adequately accommodated by establishing Colorado-specific methodologies for estimating bicycle and pedestrian volumes via a limited sample of existing counts.
