The bridge was constructed in stages, demolishing one half of bridge, keeping one-way traffic control with a traffic signal operating 24/7 on the remaining half. The team had to construct the new bridge half and switch traffic to the new bridge. Then they re-established one-way traffic signal control operating 24/7 while demolishing the remaining half bridge. Finally, they constructed the new second half of bridge to connect to the first half.

DRC’s Scott McGuire was the lead for Federal Stewardship and Oversight for the Federal Highway Administration on this project. He ensured federal requirements were met for delivery and for the disbursement and refinancing of the TIFIA loan. This Major Project added one new General Purpose lane and one new toll lane in each direction along the 16-mile corridor of I-405 between State Route 73 (SR-73) and Interstate 605 (I-605). The new tolled express lanes were combined with the existing high occupancy vehicle (HOV) lane to create two Express Lanes in each direction in the I-405 median from SR-73 to I-605. The I-405 Express Lanes included single lanes connecting to/from the SR-73 to the I-405 at the southern end of the 405 Express Lanes and to/from the I-605 and the SR-22 at the northern end of the 405 Express Lanes. The Project also included replacing 18 bridges, constructing new and widened bridges, improvements to the auxiliary lanes, relocating utilities, constructing new sound walls, and additions to the Transportation Demand Management systems.
