The June 2019 issue of Roads & Bridges features our 2019 Major Project Update, highlighting five key ongoing road and bridge projects in North America, including the Sixth Street Viaduct project in Los Angeles. Our cover story takes a look at the work on the I-59/I-20 corridor in Birmingham, Alabama—the largest project in the city's history. This issue also focuses on how the Colorado DOT responds to rockfall incidents along its highways, particularly in the Glenwood Canyon area along I-70. Lastly, we cover how the NJ Turnpike Interchange 14A Connector Bridge widening project overcame significant challenges to the benefit of a larger project.
