This dredging is in a relatively short section of the Waterway paralleling Hugh Taylor Birch State Park to the east and north of the Sunrise Blvd Bridge at Mile 1062.5. Unfortunately, this article from Soundings does not give project dates. However, the dredging is in a relatively wide section and should not impact through traffic.

Dredging set to start for ICW in South Florida
Posted on October 26th, 2015
After several years, permits were issued and a contract awarded for the dredging of the Intracoastal Waterway in South Florida, allowing the vessels that patronize the area’s waterways to have better access to local marinas and boatyards.

The dredging, which will take place from 17th Street to Sunrise Boulevard to 17 feet deep, will be the largest single public works project for the Florida Inland Navigation District, a special state taxing district tasked with managing and maintaining the Atlantic Intracoastal Waterway, according to the Marine Industries Association of South Florida.

`The Florida Inland Navigation District’s ICW dredging project will provide an extraordinary benefit to Broward County through the infusion of $20 million by increasing the depth of the ICW from the congressionally authorized depth of 10 feet to a new depth of 17 feet to accommodate the vessels that are seeking to visit, reside and retrofit at our local marinas and boatyards,’ Tyler Chappell, the Broward commissioner for FIND, said in a statement.’
