I-10 Bridge over the Mississippi River

Location: East Baton Rouge Parish     
Date Completed: 2011

On this project, Huval & Associates worked as a consultant to the construction company contracted by the LADOTD to carry out a bridge rehabilitation project.  Our team provided project-related engineering services that enabled the construction company to complete the project in a safe manner.

The rehabilitation project called for the bridge’s through truss suspended span expansion joints to be replaced with a new configuration.  All access to project work areas was to have minimal impact on traffic flow.  Our team was given the task to create a scaffolding and work platform configuration that also enabled workers to operate self-sustained for long hours and in all weather conditions.

The Huval & Associates team designed scaffolding and work platforms that provided space for a material storage area, a field office, adequate working room, and access to all work areas.  Due to the magnitude of these platforms the existing bridge was load checked for all added weight.

Challenges Encountered

• Incorporating a deflection barrier on the outside curb of the bridge deck and bridge railing repair
• Repairing and spot painting of portions of the main truss and the approach superstructure and substructure
• Preparing joint sealing details to existing finger joints on the bridge where feasible
• Workers needed  the ability to operate self-sustained for long hours and in all weather conditions
