Full Public Notice    Project Plans    Mitigation Plan

The applicant proposes to construct a new US 181 bridge to traverse the Ship Channel, 1,000 feet west of the existing bridge in Corpus Christi, Texas.  The project limits are from the US 181 and Beach Avenue intersection south to the State Highway 286 and Morgan Avenue intersection, and from Mesquite Avenue in downtown Corpus Christi west to the Interstate Highway (IH) 37 and Buddy Lawrence Avenue intersection.  The proposed project includes constructing a new bridge, demolishing the old bridge, constructing new approaches and new location roadway and frontage roads, and reconstructing the interchange at IH 37 and the Crosstown Expressway, which would include four direct connector ramps.  In order to span the Ship Channel, the proposed bridge will be a cable stay bridge, approximately 1,700 feet in length, with a minimum vertical clearance height of 205 feet above mean high water (MHW).  The bridge design includes the use of 50-foot square concrete piles and 64-foot by 174-foot rectangular concrete footings.  The bridge footings and associated bridge structures will not be placed within waters of the U.S.  The new structure will have three 12-foot lanes in each direction with 12-foot inside and 10-foot outside shoulders.  It will also include a 10-foot bicycle and pedestrian shared use path separated from the main lanes by a 2-foot concrete barrier.  Materials for construction will include steel for the main bridge span over the Ship Channel with concrete supports, concrete for elevated structures on main lanes, direct connector ramps, and asphalt for frontage roads.  Construction of the bridge approaches and frontage roads would result in 0.88 acre of permanent impacts caused by discharge of fill material into waters of the U.S.  The applicant’s plans are enclosed in 8 sheets.
