Burk-Kleinpeter,
Inc. (BKI) was contracted by the Louisiana
Department of Transportation and
Development to design the directional
interchange of a major arterial boulevard
with I-10, including elevated
structures.
BKI provided
hydraulic analysis of seven canal bridges,
topographic survey coordination, and
preliminary and final plans and
specifications. BKI designed two new
elevated directional ramps to replace the
obsolete diamond interchange at this
location. One ramp provides a direct
connection between south-bound Williams
Boulevard and east-bound I-10.
The other
directional ramp splits to provide a
direct connection from west-bound I-10 to
south-bound Williams Boulevard and to 32nd
Street. The elevated ramp design included
AASHTO concrete girder spans and curved
steel-plate girder spans. Grade roadway
improvements included realigning the
six-lane Williams Blvd. through this
interchange, aligning new at-grade ramps,
making improvements to several
intersections, and designing traffic
signalization for three new locations to
control traffic flow. Signal design
included synchronizing the new and
existing controls at Williams Boulevard
and Veterans Memorial Highway and 32nd
Street.
Estimated
construction cost is $23.9
million.
