Louisiana Department of Transportation and Development Advances $1.656 Million Mill Creek Bridge Replacement Project

en.Wedoany.com Reported - On November 9, the Louisiana Department of Transportation and Development (DOTD) announced that the Mill Creek Bridge replacement project on LA 10 near Elizabethtown in Allen Parish continues to advance. Contractor Merrick LLC has completed demolition of the old bridge and precast pile construction, and is currently pouring concrete for the pier cap beams. The project contract amount is $1,655,700, utilizing precast concrete pile foundations and concrete slab span structures. The scope of work also includes bridge deck, approach slabs, guardrails, and protective works around the bridge.

According to the official bidding quantity list, the new bridge foundation uses 18-inch diameter precast concrete piles with a planned total construction length of 2,090 feet; the bridge main structure includes approximately 158.56 cubic yards of slab span concrete and 50.27 cubic yards of pier cap beam concrete, with approximately 38,000 pounds of reinforcing steel. Approximately 3,200 square feet of cast-in-place concrete approach slabs will be constructed at both ends of the bridge deck, along with approximately 160 feet of concrete bridge guardrail and elastomeric bearings. The current cap beam pouring is a key construction step between the pile foundation and the superstructure; upon completion, work will continue on the bridge main structure and deck.

Beyond the bridge main structure, the project also includes roadway approach improvements and channel-side protection. The construction list includes approximately 436.7 tons of asphalt concrete, 1,080 square yards of old pavement milling, 102 square yards of pavement patching, and 403 cubic yards of embankment fill. Around the bridge, 716 square yards of 18-inch-thick riprap will be placed with associated geotextile to protect the abutments and surrounding slopes. After the new bridge is completed, roadway tie-in at the bridge ends, guardrail installation, pavement markings, and traffic facility restoration will also need to be completed.

On-site construction began around July 27, 2026. The Mill Creek Bridge will remain closed during construction, with detours via LA 112, LA 1156, and LA 3206. The Louisiana Department of Transportation and Development expects the bridge to reopen to traffic in February 2027, with the overall project expected to be completed in spring 2027.
