Lake Pontchartrain, rehab work on US 11 bridge - UPDATE

Date Posted: Aug 02, 2017

The contractor continues the rehabilitation work on the US 11 Bascule Bridge across Lake Pontchartrain between New Orleans and Slidell, Orleans and St. Tammany Parishes, Louisiana. The contractor will be working Monday through Friday, from 6:30 a.m. until 5:30 p.m. Work on the project has begun on the Slidell side (north) and consists of inspections, measuring of cracks, sand blasting, grinding, spall repairs and wrapping of the piers and caps as necessary. The contractor has extended the scaffolding which extends a total of 2,400 feet of cable scaffolding across Span 577 to Span 553 as this entire section has a reduced vertical clearance of 8 feet, thus eliminating the availability by recreational boaters. Decking removal is complete to Span 609 as the project moves to Orleans side (south). The work area will be marked by Danger Buoys approximately 50 feet on either side of the bridge marking an exclusion zone for vessels to stay out of the work zone. The buoys will be spaced approximately 200 feet apart and will mark the entire length of the work area. The buoys will be lighted at night with Fl W 2.5 sec lights. Mariners should avoid the area.Additionally, the contractor has six work barges (3 measuring 10 feet by 40 feet, and 1 measuring 8 feet by 30 feet, 1 measuring 30 feet by 115 feet and 1 measuring 30 feet by 120 feet with a crane height of 25 feet) and they are located near the bridge within the work zone. When the contractor is not working at night and over the weekends, the barges will be grouped together and spud down away from the navigation span and
near the work area. This equipment will be lighted by fixed white lights on each outward corner as required. During the work day, the Tug JO ANN SIMS will be monitoring VHF-FM Channel 16. The L&A Contracting Company is the contractor on the project and can be reached at (601) 270-7704, 24-hours a day. This project will take approximately 48 months to complete. In conjunction with this work, additional work beneath the
bridge on the New Orleans Side (south) will have divers placing wraps during daylight hours, issued in a separate Local Notice to Mariners for
additional information.
