Abstract:
Concrete box culvert floor slabs are known to have detrimental effects on river and stream hydraulics.

Consequences include an aquatic environment less friendly to the passage of fish and other organisms. This has

prompted environmental regulations restricting construction of traditional, four-sided box culvert structures in rivers

and streams populated by protected species. The box culvert standard currently used by the Kansas Department of

Transportation (KDOT) is likely to receive increased scrutiny from federal and state environmental regulators in the

near future.

Additionally, multiple-cell box culverts present a maintenance challenge, since passing driftwood and debris

are frequently caught in the barrels and around cell walls. As more structures reach the end of their design lives, new

solutions must be developed to facilitate a more suitable replacement. Since construction can cause significant delays

to the traveling public, systems and techniques that accelerate the construction process should also be considered.

This report documents development of a single-span replacement system for box culverts in the state of

Kansas. Solutions were found using either a flat slab or the center span of the KDOT three-span, haunched-slab bridge

standard. In both cases, the concrete superstructure is connected monolithically with a set of abutment walls, which sit

on piling. The system provides an undisturbed, natural channel bottom, satisfying environmental regulations. Important

structural, construction, maintenance, and economic criteria considered during the planning stages of bridge design are

discussed.

While both superstructural systems were found to perform acceptably, the haunched section was chosen for

preliminary design. Rationale for selection of this system is explained. Structural modeling, analysis, and design data

are presented to demonstrate viability of the system for spans ranging from 32 to 72 feet. The new system is expected

to meet KDOT’s needs for structural, environmental, and hydraulic performance, as well as long-term durability.

Another option involving accelerated bridge construction (ABC) practices is discussed.
