LADOTD Structure No. 02380620200432
Recall No. 002500



Description of the Bridge

The LA 23 Intracoastal Waterway (ICWW) /Judge Perez Bridge (Structure No. 02380620200432, Recall No. 002500, Louisiana Historic Resource Inventory No. 38-00017) is a steel vertical lift bridge built in 1967 to carry LA 23 traffic over the ICWW. It is located in Belle Chasse, Plaquemines Parish (approximately latitude 29.871715, longitude -90.008684). The overall bridge length is approximately 2558 feet, including its pre-stressed concrete stringer/multi-beam and steel girder approaches. The main lift span is approximately 150 feet long by 34 feet wide. The main span with the lift towers is approximately 250 feet long.


National Register of Historic Places 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 tower drive vertical lift bridge has significance as a movable bridge and as an important variation within the vertical lift bridge type. Distinctive engineering features that convey this variation include the location of two separate motor and drive mechanisms, which power the two sheaves on each tower. This bridge appears to conform to a state standard plan (SL50-150-28). The bridge exhibits alterations to the operator’s house and replacement of isolated mechanical components and counterweight ropes that results in a minor loss of integrity, but continues to convey the significant design features of this variation within the vertical lift type. This bridge is eligible for listing in the National Register under Criterion C: Design/Engineering. No evidence was found during research or data collection activities to indicate that this bridge possesses a direct and important association with historical events or trends. This bridge does not possess significance under Criterion A.


Status of the Bridge

The bridge is owned by LADOTD and currently carries LA 23 westbound traffic across the ICWW.

The New Orleans Regional Planning Commission (NORPC) and LADOTD in conjunction with the FHWA propose improvements to the LA 23 crossing of the ICWW that would involve the bridge and the neighboring LA 23 Belle Chasse Tunnel (Structure No. 02380620200621, Recall No. 002510). The tunnel handles LA 23 eastbound traffic. A number of alternatives have been considered, including rehabilitation of the bridge and tunnel or demolition of the tunnel with replacement of the bridge. The preferred alternative, pending environmental approval, will include demolition of the tunnel and construction of a new four lane fixed bridge on an adjacent alignment to accommodate eastbound and westbound LA 23 traffic and allow uninterrupted traffic on LA 23 and the ICWW. The current LA 23 ICWW/Judge Perez Bridge, if not transferred to a new owner, would be demolished.

The LA 23 Judge Perez/ICWW Bridge was included in LADOTD’s Historic Bridge Inventory and was categorized as a Preservation Candidate for Historic Preservation due to its condition and configuration and the possibility that it may or may not be modified to meet transportation criteria and the U.S. Secretary of the Interior standards for the treatment of historic bridges. 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 September 21, 2015, hereinafter referred to as the Historic Bridge Programmatic Agreement (HBPA), viewable at this web link:

Pending environmental approval, the preferred alternative would result in an adverse effect to the historic bridge. As per the HBPA Stipulation (VII.D.1, 2 and 5), to partially mitigate the Adverse Effect to this historic bridge, the bridge is being marketed to other entities for non-vehicular, adaptive re-use for historic preservation either at its current location or in another location.

Re-use of the towers and main lift span portion as a non-vehicular bridge is encouraged. If the bridge were to be repurposed across a navigable waterway, such as the ICWW, the lift span would need to follow U.S. Coast Guard requirements for location (33CFR114) and remain operational, (33CFR117.7), which states that any owner of a drawbridge must:

· Provide the necessary drawtender(s) for the safe and prompt opening of the drawbridge.

· Maintain the working machinery of the drawbridge in good operating condition.

· Cycle the drawspan(s) periodically to ensure operation of the drawbridge.

· Ensure that the drawbridge operates in accordance with the requirements of 33CFR117.


If the bridge is moved to a non navigable waterway, the lift span would not necessarily need to be operational, depending on jurisdictional agency requirements. Parties interested in acquiring this bridge for adaptive, non-vehicular use should read the stipulations for bridge ownership transfer below. This bridge will be marketed until May 22, 2018. If ownership of the bridge is not transferred to another entity, it will be demolished.


Contact Carey Coxe at or 225-242-4520 by May 22, 2018 if you are interested in acquiring this bridge for non-vehicular, adaptive re-use or if you have questions on submitting a proposal.


Approximate Dimensions of the Bridge

The overall bridge length is approximately 2558 feet by 34 feet wide, including its prestressed concrete stringer/multi-beam and steel girder approaches. The main lift span is approximately 150 feet long by 34 feet wide. The main span with the lift towers is approximately 250 feet long.


Funds for Adaptive Reuse of the Bridge

Costs associated with preservation of the bridge  by a new owner, such as lead abatement, transportation, engineering, reassembly, etc., either in its current location or at another location, would be eligible for reimbursement to the new owner in a total amount not to exceed the estimated demolition cost.  Payment of the salvage value (see below) by the new owner to LADOTD would not be a reimbursable cost.   

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 structural steel portion which is estimated to be $101,002. This amount would not be a reimbursable preservation cost.  Should the entire lift span not be desired, LADOTD may consider transferring ownership of select portions of the bridge, with salvage value to be adjusted accordingly.

The bridge may have lead paint requiring abatement which would be the responsibility of the entity who acquires the bridge. 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 (i.e., cars and trucks).

If the bridge remains in its current location or is transferred to another navigable waterway, it must remain operational, as per U.S. Coast Guard requirements (33 CFR Parts 114 and 117).

If the bridge is relocated, relocation and reassembly will be the responsibility of the entity taking ownership.

The proposed use of the transferred bridge will be subject to the approval of FHWA, LADOTD, and LASHPO.

The entity will be required to execute a preservation agreement that will include the above stipulations.

Attn: Carey Coxe

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 location?


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 LASHPO. 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.
