The expansion of I-10 from Causeway Boulevard to the 17th Street Canal will relieve traffic congestion at the Causeway Boulevard interchange. Traffic congestion has been steadily increasing in this area for years as a result of the rapid population growth and urban development occurring on Lake Pontchartrain's north shore. This section of I-10 is one of the most traveled roads in Louisiana.

Work on the 1.9-mile stretch of interstate includes adding a fourth lane on each side of the roadway, constructing a second lane on the entrance and exit ramps at the Causeway and Bonnabel Boulevard interchanges, and the relocation and upgrade of water and sewer mains along the I-10 service roads.

The new roadway is being constructed with asphalt that is formulated to lengthen the life of the pavement and lower long-term maintenance and repair costs.
