Delaware Paving

On June 8, 2021, a hazardous materials incident led to a ten-hour closure of I-95. In response, Diamond Materials promptly assisted the Delaware Department of Transportation (DelDOT) and the State of Delaware's Department of Natural Resources and Environmental Control (DNREC) by providing crews and materials for emergency pavement repair. This effort successfully restored full traffic flow on I-95. Diamond Materials extends gratitude to their paving and milling crew for their quick and safe resolution of the situation.

SR1 NE Front Street


On May 18, 2019, a ribbon-cutting ceremony led by Jennifer Cohen, DelDOT Secretary of Transportation, and others from DelDOT and Diamond Materials, marked the opening of the new overpass on NE Front Street in Milford, Delaware. This project, which broke ground on February 19, 2018, and was scheduled for completion by December 21, 2019, was remarkably completed six months ahead of schedule and on budget. The SR-1, NE Front Street project involved constructing an overpass over SR-1 to provide a safer connection for residents to the City of Milford, replacing a previously hazardous at-grade intersection. The comprehensive project included on and off ramps, lighting, drainage systems, concrete curbs, a shared use path, and the relocation of several utilities. Diamond Materials' commitment to quality, safety, and efficient project management, even under harsh weather conditions, was instrumental in the project's success. This achievement highlights the importance of a skilled workforce, including project managers, office personnel, superintendents, foremen, operators, laborers, and subcontractors, demonstrating that a well-coordinated team is crucial for successful heavy highway construction projects.

SR1 - SR 72 Diverging Diamond Interchange Project

The SR1-SR72 interchange reconfiguration in New Castle County, DE, addressed traffic congestion and safety concerns in an area surrounded by businesses, residential communities, schools, and parks. The Delaware Department of Transportation (DelDOT) opted for a design-build approach to expedite the project, choosing a Diverging Diamond Interchange (DDI) – Delaware's first – to transform the existing traditional diamond interchange. This innovative design, recognized by Popular Science magazine for its traffic engineering innovation, improves traffic flow and safety by allowing uninterrupted left turns and eliminating the need for dedicated left turn signals. Diamond Materials, in collaboration with JMT, successfully completed the $7.1M project in November 2016, a month ahead of the scheduled December completion, winning acclaim from DelDOT and receiving the ACEC DE 2017 and ACEC MD 2018 Outstanding Project Awards.

Airport Road

The Airport Road Rehabilitation project, executed in Milford, DE, was designed by Davis, Bowen & Friedel, Inc. to refurbish the deteriorating Airport Road. This comprehensive project included hot-mix wedging to achieve finish grade elevations, a half-inch milling of the existing roadway coupled with a two-inch overlay, regrading of ditches, as well as sidewalk and curb replacements to comply with ADA standards, and widening of the existing shoulder. The primary objective was to address the road's existing issues and enhance safety for travelers. During construction, Diamond Materials identified and repaired several areas where the subgrade had failed, collaborating with the City of Milford to deliver a durable and improved roadway.

Willow Grove

The Willow Grove road project, managed by DELDOT, involved the removal and replacement of the existing concrete roadway in Willow Grove, Delaware. Key aspects of the project included detouring traffic, rubblizing the existing concrete, excavating and preparing the subgrade, and laying a full depth of 10-inch PCC pavement, with a total of 3,600 cubic yards of concrete placed. Due to the absence of a central mix plant nearby, Diamond Materials implemented an innovative solution by offloading mixer trucks into tri-axle dumps for efficient concrete placement. The project, which presented unique challenges due to the nature of concrete replacement, demonstrated Diamond Materials' adaptability and teamwork. James Osborne, a Design Support Engineer at DELDOT, praised Diamond Materials, Century Engineering, and DELDOT specialists for their collaborative effort in successfully completing this complex project.

Cranbury - Half Acre Road

Diamond Materials recently commenced construction work on a large warehouse facility on Half Acre Road in Cranbury, New Jersey. The project involves two warehouses, each spanning 1,000,000 square feet, for which Diamond Materials is responsible for all the necessary site work and paving. The project started on March 26, 2019, and is targeted for completion by December 31, 2019.

Post Acute Medical Center

Diamond Materials recently contributed to the construction of Dover, DE's only freestanding medical rehabilitation hospital, which opened in Spring 2019. The 42,000 square-foot facility aims to rehabilitate patients for a return to community settings, including assisted or independent living. Diamond Materials' role encompassed comprehensive sitework, including grading, curb work, paving, and stone installation for the parking lot. They also installed a storm tech system and water and sewer utility lines. Notably, Diamond Materials implemented an innovative approach by installing a Pervious Concrete sidewalk, a less common but environmentally beneficial feature that aids in groundwater recharge, reduces stormwater runoff, and aligns with U.S. EPA stormwater regulations.

US 13 Port Penn Road Intersection

The US 13 & Port Penn Road Intersection project, part of the larger US 301 Mainline initiative, aimed to create a four-lane limited access road. The US 301 project stretches from the Maryland/Delaware state line near Middletown to the vicinity of Armstrong Corner Road, then crosses existing US 301 and Boyds Corner Road, before connecting to SR 1 south of the C&D Canal in New Castle County, Delaware. A key element of this contract was enhancing intersections at US 13 and Port Penn Road to facilitate toll-free access to SR 1. Initially planned for 789 calendar days, the project was completed by Diamond Materials nearly six months ahead of schedule and significantly under the budget, thanks to effective planning and teamwork with the Department of Transportation.
