Mega-ton girder placement over La Jolla Village Drive in San Diego

On Friday, Feb. 8, San Diego Association of Governments (SANDAG) crews closed La Jolla Village Drive to thru traffic at Genesee Avenue in the University City area to set 60-ft-long concrete girders, or beams, to construct the elevated guideway for the future Mid-Coast Trolley. Crews hoisted the 95-ton precast girders using a crane and set the girders on the columns that were built at the intersection. The girders were trucked from Riverside on special industrial trucks built to withstand extra-heavy loads. Over the next several days the concrete continued hardening and gaining strength. Last week, high-strength steel cables were installed and tensioned inside the beams, allowing support towers in the intersection to be removed and the intersection to be opened by the morning of Friday, Feb. 15. The Mid-Coast Trolley Project will extend Blue Line Trolley service from Old Town north to the University City community. Nine new stations will be constructed. Major construction work began in 2016, with service anticipated to begin in 2021.

I-4 Ultimate Improvement Project—Orlando, Fla.

The I-4 Ultimate Improvement Project is a P3 effort involving reconstruction and expansion of a 21-mile stretch of I-4 that moves into the heart of Orlando, Fla. Work on the project began in 2015, and the project limits run between Orange County and Seminole County. Due to the scope of the project, crews had to follow a strict traffic management and safety protocol policy in order to keep both traffic flowing during construction and minimize traffic- and work-related incidents. At the time of Roads & Bridges' visit to the I-4 worksite, the Grand National Drive Overpass was open to traffic and crews were preparing to close up the summer season.

Video: Illinois uses 3-D laser scanners

Several Illinois Department of Transportation (IDOT) districts have recently begun using a 3-D laser scanner in construction and surveying operations. IDOT began a research implementation project several years ago where the technology was a viable solution for IDOT crews. The implementation stage of the project is studying the benefits that a 3-D intersection provides in the area of worker safety. The technology provides a 3-D graphical image of the intersection. Eventually, the agency hopes that all IDOT districts will have a 3-D laser scanner to use for construction and design purposes.

Construction crews on the Ohio River Bridges Project Downtown Crossing are working to change the landscape of downtown Louisville, Ky., and southern Indiana. The addition of lanes and the reduction of conflict points on the project are helping to improve traffic flow and safety.

The Jane Byrne Interchange is the confluence of I-90, I-290, and Congress Parkway. With more than 400,000 vehicles traveling through the interchange daily and more than 900 crashes annually, it rates as one of the worst bottlenecks in the country. Among the project's major challenges has been maintaining a comprehensive traffic management plan amidst persistently heavy traffic.
