Our subsidiary, Judlau Contracting, addressed safety, operational, and capacity deficiencies at the I-55 and Weber Road Interchange, a critical commuting link that serves local businesses and industries. The $48 million contract added a third lane in each direction of 1.6 miles of Weber Road, a north-south artery. The reconstruction of the existing interchange as a diverging diamond interchange was also part of the work scope. Considerable improvement in traffic flow due to the additional lane and interchange reconstruction is expected, which is critical to the area as it has experienced significant growth in population in recent years. To carry out the contract, Judlau reconstructed I-55 ramps, built dual 252-foot-long, 60-foot-wide bridges and retaining walls, and installed interconnected traffic signals through the interchange. Placement of sidewalks, in addition to the installation of overhead sign structures, CCTV cameras, fiber-optic connections, and continuous LED roadway ligh

Judlau devised innovative solutions to logistical challenges inherent in working in a densely populated, urban location. Minimal work areas left little room for the construction of the foundations and towers that were necessary to support the temporary bridges needed to maintain traffic at existing levels of service during construction. The crews worked around existing fiber-optic and intelligent transportation system cables that could not be moved or interfered with due to the security concerns around the busy bridge. Judlau completed the design and construction of the entire temporary ramp with three temporary bridges in eight months. The subcontractor crews assembled more than six temporary bridge spans on the ground and transported them on rolling dollies from the staging area and erected them over I-95 roadways using large cranes.

OHLA USA's subsidiary, Judlau Contracting, Inc., served as general contractor to install 2.6 miles of 24-inch, 36-inch, and 48-inch trunk water mains that connect to shafts that service NYC's Water Tunnel No. 3. Work to replace varying-sized sewers and 12-inch, 20-inch, and 24-inch distribution water mains was also part of the $338 million contract. Logistics were extremely challenging in several areas, particularly the section on 9th Avenue between West 58th and West 59th, which required the relocation of a massive utility duct bank to make way for the installation of a 36-inch trunk water main and butterfly valve chamber. Since the job site was highly visible to nearby residents and business owners and featured extensive pedestrian and vehicular traffic alongside the narrow work area, the project team took the utmost care in keeping it safe and clear of debris at all times.
