| 摘要： | Flatiron West, Inc. widened this stretch of highway in Orange County, one of the most populated counties in the United States. The project gives motorists an additional general-purpose lane in each direction, while also improving on- and off-ramps to help with current and future travel demands. This multi-segment project, expected to be finished in mid-2024, will feature seven bridges in three locations (La Paz, Oso Parkway, and EI Toro Railroad), and a full interchange reconstruction at La Paz Road. Construction of 22 retaining walls of multiple types and mechanically stabilized earth (MSE) systems are required for the complexity of this project. Flatiron must manage large-scale paving operations as a part of the improvements to the interstate, while also providing significant improvements to drainage and electrical infrastructure installations that involve over 100 drainage systems and over 3 miles of electrical infrastructure installations. Segments of this work is on, over, and adjacent to active freight and commuter rail lines and over ancillary waterways, which require the management of environmental permitting. |
