E 543 Overpass Versus Underpass | Bureau of Engineering
The greater grade differential usually means higher costs due to additional grading or wall construction, longer pavement lengths, and additional right of way. Comparative costs of the

Underpasses work best when designed to feel open and accessible. Underpasses are significantly less expensive when built as part of a construction or reconstruction project and generally offer gentler
California budgets $61.5 million for wildlife crossings
Underpasses are generally cheaper than overpasses, and some animals, such as deer, prefer them. Mountain lions, however, prefer overpasses.
Wildlife-Vehicle Conflict, Crossing Structures, and Cost Estimates
Although construction costs for wildlife crossing infrastructure can vary widely depending on the terrain, soils, hydrology, number of lanes of traffic, structure dimensions, construction materials, and other
Flyover vs. Underpass
The cost of constructing flyovers and underpasses can vary depending on several factors, including the length, complexity, and location of the project. Flyovers generally require more materials and
Revenue Options for Wildlife Crossings
Structures vary in scope and scale, with cost ranging from less than $1 million for a small underpass to $6–7 million for a larger structure such as a double span overpass.

Type of underpass bridges. This paper presents the total cost and cost distribution between activities required for the construction of reinforced concrete underpass bridges.
Design Considerations for Wildlife Crossings
When evaluating the cost five years prior and post construction, this reduction in WVCs amounts to roughly $664,636 in savings ($110,773 per year). So in less than five years, the construction project
Wildlife Crossing Ahead: Costs and Benefits of Avoided Collisions
With $5 million of the overpass being federally funded and maintenance costs being state funded, the WS appears to be overly dependent on federal funding. State policymakers can use this study to
Chapter 2: The Basics, Costs, and Benefits of
Using this framework, managers are able to calculate cost-benefit thresholds for a variety of mitigation measures. For example, the average cost (in 2007 U.S. dollars) of building and maintaining a wildlife
