LOWELL, MASS. – TRC Companies, Inc. was honored on December 6, 2011 by the Orange County Chapter of the Women’s Transportation Seminar (WTS) for its role in the I-5 Gateway Reconstruction Project. The project received the WTS Innovative Transportation Solutions Award at the Chapter’s annual Awards and Scholarship Gala.
The I-5 Gateway project involved reconstructing and widening two miles of freeway; adding one mixed flow lane and one HOV lane in each direction; and constructing six bridges, three bridge approaches, one pump station and three retaining walls. The project was completed for the Orange County Transportation Authority (OCTA) and Caltrans District 12 through a unique public-private partnership.
“TRC is proud to be part of this innovative project to improve Orange County’s transportation infrastructure,” said Ross Lew TRC Project Manager and Engineer of Record for the northern segment of the I-5 widening in Orange County. “We are dedicated to helping clients like OCTA solve complex challenges and deliver results to the communities in which we live and work.”
TRC was responsible for project management, design oversight, stage construction design and traffic handling, and construction support. The project included an innovative use of a seal slab to prevent ground water from reaching the roadway surface, which eliminated the need to collect, treat and dispose of groundwater. Other elements also included complex shoring systems to maintain nearby rail traffic during construction and the design of a catenary system to protect a fiber optic telephone line during bridge construction.
