InfrastructureUSA.org is a non-profit, online community whose mission is to bring together infrastructure experts, industry leaders, government officials and most especially interested citizens, to participate in vigorous conversation and generate action to address the U.S. infrastructure crisis.

The following projects are finalists to receive the American Society of Civil Engineers (ASCE) Outstanding Civil Engineering Awards. 

The winner, one of the among five finalists, will be revealed at ASCE’s OPAL Gala, March 15, in Arlington, VA.

Elizabeth River Tunnels Project

Location: Norfolk and Portsmouth, VA

Project Owner: Virginia Department of Transportation

The new, 3,800-foot Midtown Tunnel is the first concrete, deep-water, immersed tube tunnel in North America. The rectangular reinforced concrete design allowed for increased durability at reduced cost. The team tested more than 100 different high-performance mix designs to optimize compressive strength, flowability, shrinkage, set time, and durability.

I-90 Fox River Bridge

Location: Elgin, IL

Project Owner: Illinois Tollway

The I-90 Fox River Bridge Project featured the removal of an aging six-lane twin bridge and the construction of a new eight-lane twin bridge on the same alignment, all while maintaining six lanes of open traffic throughout the process. How? Stanley Consultants designed a “bridge under a bridge” construction concept using a space-saving gantry system for beam erection.

Folsom Dam Auxiliary Spillway, Phase IV

Location: Folsom, CA

Project Owner: U.S. Army Corps of Engineers

The spillway, a cooperative effort between the U.S. Army Corps of Engineers and the Department of the Interior, prevents overtopping of the Folsom Dam while providing downstream Sacramento protection against 200-year flood events. Kiewit and the USACE team used aerial drones to scan and map cleaned rock surfaces prior to the placement of the dental concrete. Conventional geologic mapping methods were impractical and ineffective due to difficult access in many areas. The use of drones made the operation much safer and produced a higher quality surface.
