Complete renovation of 15-mile highway section with safety improvements and modernization
The State Route 42 Highway Renovation Project involved the comprehensive rehabilitation of a 15-mile section of aging highway that had reached the end of its service life. This critical infrastructure project addressed deteriorating pavement, outdated safety features, and inadequate drainage while implementing modern traffic management systems to improve safety and efficiency for the 4,500 daily vehicles that use this vital transportation corridor.
The existing highway suffered from severe pavement deterioration, with multiple areas requiring complete reconstruction. The project needed to be completed while maintaining traffic flow on this critical transportation route, requiring innovative traffic management solutions and accelerated construction techniques. Additional challenges included coordinating with utility companies for underground work and minimizing disruption to adjacent businesses and residents.
KGM Construction implemented several innovative approaches to overcome project challenges:
Complete removal and replacement of deteriorated asphalt with new high-performance pavement designed for 20-year service life
Installation of new guardrails, rumble strips, and improved signage to enhance driver safety and reduce accidents
Reconstruction of drainage systems with larger capacity culverts and improved stormwater management
Implementation of smart traffic management systems including variable message signs and traffic monitoring
95% of existing pavement materials recycled and reused in the new construction, reducing waste and material costs
Advanced stormwater treatment systems to improve water quality and reduce environmental impact
Comprehensive erosion and sediment control measures throughout construction to protect adjacent waterways
LED lighting for all new fixtures and energy-efficient materials reducing long-term operational costs
Innovative approaches to highway renovation
Comprehensive pavement condition survey using advanced ground-penetrating radar and core sampling to identify areas requiring full reconstruction versus overlay. Development of detailed construction sequencing to minimize traffic disruption.
Implementation of full-depth reclamation techniques where existing pavement and base materials were pulverized and mixed with cement to create a new stabilized base, reducing material waste and construction time.
Use of hot in-place recycling for pavement sections in better condition, heating the existing asphalt, scarifying it, mixing with rejuvenating agents, and recompacting to restore pavement quality with minimal new material.
Continuous quality control testing including nuclear density testing, asphalt content verification, and smoothness measurements to ensure compliance with specifications and long-term performance.
Enhancing highway safety for all users
Installation of modern guardrail systems meeting current safety standards, including energy-absorbing end treatments and improved crashworthiness.
Centerline and shoulder rumble strips to alert drivers when they are drifting from their lane, reducing run-off-road accidents by 40%.
High-visibility signage with retroreflective sheeting and proper placement to improve driver awareness and reaction time.
LED lighting at intersections and interchanges providing better illumination with lower energy consumption and maintenance costs.
