Nashville, Tenn.’s signature downtown arterial, named Broadway, will soon boast a new gateway bridge to make travel safer and more efficient. Built by Kiewit Corp. under a construction manager-general contractor delivery for the Tennessee Dept. of Transportation, the $71-million Broadway Viaduct occupies the same footprint as its deteriorating 75-year-old, 700-ft long, 98-ft-wide predecessor, spanning a major urban avenue, five railroad lines and two greenways. A two-month shutdown of the heavily traveled corridor enabled Kiewit to demolish the old bridge and erect a new steel structure, designed by Gresham Smith. Scheduled for completion in late October, the bridge will provide six 10-ft-wide travel lanes, an 8-ft-wide striped median and 11-ft, 8-in.-wide sidewalks.
Denali National Park Road Improvements
Construction is underway on the $51.1-million earthworks package for the Polychrome Area Improvements Project. The CM-GC project for the Federal Highway Administration includes blasting and stabilization of rock slopes adjacent to an active landslide to support the construction of a 475-ft-long single-span steel truss bridge, restoring access for visitors. Granite, which handled long-lead material procurement, will also mobilize equipment and build support facilities.The entire project is scheduled to be completed in 2026.
SunRail Phase 2, North Expansion
The $43-million project within the Central Florida Rail Corridor will extend the Florida Dept. of Transportation’s SunRail commuter rail service by more than 12 miles. Civil, structural, track and operational system improvements will enable passenger trains to operate safely at speeds up to 79 mph. The extension is scheduled to open in the summer of 2024.
MTA Rockaway Line, Rehabilitation and Resilience Project
To minimize the effects of future storm events on the heavily used New York City subway line linking the Borough of Queens with the Rockaway peninsula, the design-build team of Schiavone and EXP Services P.C. will design and construct viaduct repairs at multiple locations, implement resilience and flood mitigation elements, upgrade utilities and install signal and operations infrastructure. The $392-million project is set for completion in 2026.

The $1.24-billion design and reconstruction project will improve connectivity across the six terminals. The effort includes roadway reconfiguration, intuitive wayfinding and enhanced traffic technologies, retaining walls and utility relocations and upgrades. The Ground Transportation Center will have a 1,950-space vehicle parking facility equipped with electric vehicle charging stations and an eco-conscious timber facade, a 400-ft-long elevated pedestrian bridge, a rainwater harvesting facility and provisions for solar paneling. The project is slated to be completed by the end of 2027.
