 In an effort to ease congestion along
two miles of urban Interstate 10, the Louisiana
Department of Transportation and Development
selected Burk-Kleinpeter, Inc. to design the
addition of a fourth through-lane and median
shoulders to eastbound and westbound I-10. The
addition will tie into the recently widened
I-10/I-610 Split project at the Southern Railroad
underpass and end at the Tulane Ave. Interchange.
The project also includes widening the Metairie Rd.
interchange and adding a new pump station and noise
barriers.
Widening the Metairie Rd. overpass requires that the
I-10 westbound entrance and exit ramps along the
railroad be moved out. New retaining walls will be
installed along the railroad to make room for the
ramps. Straddle bents will be used to tuck the
frontage road under the widened overpass along the
Metairie cemetery.
The new 850-CFS pump station, designed to drain the
Metairie Road and railroad underpasses, can handle
up to a 100-year storm. Noise barriers, for the area
and for the newly completed I-10/I-610 split
improvements, will be constructed with at-grade
concrete panels along the roadway and with
lightweight metal along the bridges.
The sequence of construction is a key aspect in
maintaining a minimum of two lanes of traffic in
each direction while constructing over the existing
alignment.
Construction will cost approximately $60.5 million.
