Prefabricated Pedestrian WEI has designed pedestrian bridges having conventional, spread, slab, and pile foundations. Design focus has been on ease and speed of installation, cost, stability and function, lack of disruption to the surrounding area, and beauty.
Pre-Cast WEI has also designed for pre-cast vehicular bridges, including an arterial bridge with a 22' span where utility relocates, excavation, placement, backfill, and readiness for operation had to occur over a 3 day weekend, and the road was open by Monday evening!
Field Constructed WEI also provides full service in designing larger field cast and fabricated bridges. Site work design is handled by WEI including; utility locates, relocates, and coordination; traffic routing, detouring, and bypasses; hydrology and hydraulic evaluations; approach design; grading and drainage; and permitting and coordination. WEI subcontracts support services including: surveying; potholing; geotechnical exploration; and the bridge structure design which, actually, is not the major work involved in a bridge design project, but rather the site work provided by WEI.

Mill Creek Flood Control Parkway
Project (Phase 2, 4, & 5), Moab, UT
Metric design and construction oversight
of concrete bike & pedestrian paths, jetties,
channel improvements, creek crossing,
arterial underpass, crossing under UDOT
bridges, and permitting. Project also
included design of minor arterial road
widening. The underpass was 22' wide
and 9' high, and doubled as a pedestrian
underpass and overflow flood control
structure. As noted above, the particular
challenge was to perform all utility
relocates, excavation of the roadway,
plaacement of the foundation, 3-sided
pre-cast bridge structures, and have
everything completed and ready for
opening traffic in 3 days -- and it was. Good
planning, tight specifications, and
fortunately a good contractor brought it all
together.
Mill Creek Flood Control & Parkway
Project Phase III, Moab, UT
Design concrete bike/pedestrian paths,
riverside improvements, pedestrian bridge
abutments and permitting.

D-1/2 Road Pathway Project,
Mesa County, CO
As part of 2 mile 8' wide pathway
project, designed roadside
pedestrian bridge.
Scott M. Mattheson Wetlands
Project, Moab, UT
Bridge hydraulics & abutment
design and associated permitting.
Client was very particular about
not disrupting the environment.
Design approach was to have
narrow crane back up to creek on
path, drive piles, repeat on the
opposite side, unload pre-fabricated
bridge, and carefully swing and
weave it around and through
branches and set. And it worked
-- not a single branch was scarred.
Cannon Site Access, Moab, UT
Evaluated hydraulics in Mill Creek
and designed bridge abutments.
Mill Creek Project Phase I,
Moab, UT
