US 90 OVER I-10
ROUTE: US 90
CALCASIEU PARISH, LOUISIANA
STRUCTURE NUMBER 07100030405781
RECALL NUMBER 031450
Description of the Bridge
The US 90 Bridge over I-10 (Structure Number 07100030405781, Recall Number 31450, Louisiana Historic Resource Inventory No. 10-00499) is a two lane, one way, steel plate girder bridge constructed in 1959. It is located in Lake Charles in Calcasieu Parish (approximately latitude 30.236806, longitude -93.279389). The overall bridge length is approximately 1172 feet, while the girder spans are approximately 650 feet in length.
National Register Eligibility
Through consultation between the Louisiana Department of Transportation and Development (LADOTD), the Federal Highway Administration (FHWA), the Louisiana State Historic Preservation Officer (LASHPO) and the Advisory Council on Historic Preservation (ACHP), the bridge has been determined eligible for the National Register of Historic Places (NRHP). This steel girder bridge has significance for its association for its main span lengths. The bridge has four main plate girder spans: two are 150 feet and two are 175 feet, which are considered exceptional main span lengths for steel plate girder bridges. The bridge piers also display innovative or complex technological solutions related to geometric constraints. The narrow configuration of the pier, along with the fabricated steel construction of the pier shaft and cap and the hold-down anchor attachments to the concrete foundations, further lend to the engineering complexity of this bridge. The bridge retains good integrity and conveys exceptional significance for its length. Therefore, it is eligible for the National Register under Criterion C: Design/Engineering.
Status of the Bridge
The bridge is owned by the Louisiana Department of Transportation and currently carries US 90 westward vehicular traffic over Interstate 10. LADOTD in conjunction with the FHWA proposes replacement of the bridge under State Project No H.003931 and Federal Project Number H003931. A number of alternatives have been considered, including rehabilitation of the bridge, using the bridge in a one way pair, bypassing and adaptive reuse, and demolition with replacement of the bridge. The preferred alternative includes removal and replacement of the bridge. The estimated replacement date is to be determined.
As a mitigation stipulation for the Adverse Effect to this historic bridge, the bridge is being marketed to other entities for historic preservation. If ownership of the bridge is not transferred to another entity for moving to another location for an alternate use, the bridge will be demolished.
The US 90 Bridge over I-10 was included in LADOTD’s Historic Bridge Inventory and was categorized as a Preservation Candidate for Historic Preservation due to its condition and the possibility that it could not be rehabilitated or modified to meet the project purpose and need and the U.S. Secretary of the Interior standards for the treatment of historic bridges. Additionally, it was included in the Programmatic Agreement Among the FHWA, the LADOTD, the ACHP and the LASHPO regarding Management of Historic Bridges in Louisiana, executed August 25, 2015, (viewable at this web link

Re-use of the bridge as a non-vehicular bridge is encouraged. If you are interested in acquiring this bridge for adaptive, non-vehicular use please read the stipulations for bridge ownership transfer below. This bridge will be marketed until September 7, 2022. Contact Katherine Sinitiere at katherine.sinitiere@la.gov or 225-242-4509 by September 7, 2022 if you are interested in acquiring this bridge for non-vehicular, adaptive re-use or if you have questions on submitting a proposal., 2022 if you are interested in acquiring this bridge for non-vehicular, adaptive re-use or if you have questions on submitting a proposal.
Dimensions of the Bridge
The overall bridge length is approximately 1172 feet. The actual spans of the bridge are 150 feet (2 spans) and 175 feet (2 spans).
Funds for Relocation and Reuse of the Bridge
Funding that would be used for demolition of historic bridges can be used for its preservation at a new location. The estimated cost of demolition of the US 90 over I-10 Bridge is $1,969,000. An amount not exceeding this estimated cost of demolition ($1,969,000) would be made available to the new owner as a reimbursement for relocation and historic preservation of the bridge.
Stipulations for Bridge Ownership Transfer
The entity receiving the bridge must agree to the following:
The new owner would be charged the salvage value of the bridge which is estimated to be $895,000. (According to Title 7 Section 14(A) of the Louisiana Constitution, property or things of value of the state shall not be donated to or for any person, association, or corporation, public or private).
The entity must accept full ownership and all financial and legal responsibilities, including, but not limited to, maintenance, liability, and permitting.
The entity shall ensure that the transferred bridge is closed to motorized vehicular traffic (e.g., cars and trucks).
If the bridge is relocated, the relocation, reassembly and necessary permitting will be the responsibility of the entity taking ownership.
The proposed use of the transferred bridge will be subject to the approval of FHWA Louisiana Division (lead federal agency), LADOTD (lead state agency), and Louisiana State Historic Preservation Office (LASHPO).
The entity will be required to execute a preservation agreement that will include the above stipulations.
Submitting a Proposal
Interested parties must submit a proposal to LADOTD in writing (either by email or letter) of their interest by September 7, 2022. Please reference project number H.003931 in your proposal.

P.O. Box 94245
Baton Rouge, LA 70804-9245
Attn: Katherine Sinitiere
The proposal must address:
Location and use: Where will the bridge be relocated, what will be its new use, and how it will be made accessible to the public?
Setting: Will the bridge continue to maintain a similar crossing as its original site, such as a water crossing or as a separation structure? Does the proposed relocation site have a similar setting as the original?
Assumption of responsibilities: The new owner must demonstrate understanding of the specific responsibilities they will take over when ownership is transferred, including title and insurance. The proposal must specifically discuss that the new owner will:
a) Maintain the bridge and the features that give the historic bridge its historic significance for a period of at least 20 years; and
b) Assume all future legal and financial responsibility for the historic bridge, which may include an agreement to hold the state transportation department harmless in any liability action.
Rehabilitation: Are there plans prepared for the rehabilitation of the structure on site? Do the plans meet the Secretary of the Interior Standard? In the case of disassembly, are disassembly plans prepared?
Requirements and studies: Describe any additional special requirements for the reuse of the bridge (e.g., if the bridge will be used for pedestrians, railing geometry and capacity restrictions for this use should be considered) and any additional studies or environmental clearances that are needed for the relocation, including potential archaeological survey of new site.
Cost estimate of the cost to relocate the structure and the reinstall at new site, including how funds will be obtained or raised.
Schedule: Outline of the proposed relocation schedule, addressing ability to have bridge off its current site by the scheduled replacement date (to be determined by LADOTD) and plans for temporary storage of the bridge, if needed.
Evaluation of Proposals
Proposals will be reviewed by a selected committee including representatives of LADOTD environmental and bridge staff, and the LA State Historic Preservation Office. Each proposal will be reviewed and evaluated based on how well it meets the above proposal criteria.
If the first choice in owner withdraws from the process prior to relocation, the bridge will not be re-marketed. Rather, the review committee's second choice in owner, if any, will be selected. The timeframe for relocation will not be re-started with the re-selection; however, a relocation extension may be granted at the owner's discretion. If there is no proposal that meets the above proposal criteria, then the bridge can be demolished.
Schedule for review of proposals
Proposals will be reviewed within 2 months of submittal deadline.
