The American Institute of Steel Construction (AISC) has released the new Guide to Steel Highway Grade Separation Bridges, a comprehensive industry resource designed to support the planning, design, and construction of steel highway overpass structures. The guide is now available through AISC's Bridge Resource Center.
CHA is proud to have played a leading role in developing this national publication. Mike Culmo, PE, Chief Engineer, served as principal author of the guide, bringing decades of experience in bridge design, accelerated bridge construction, and transportation infrastructure delivery.
As agencies across the country seek durable, cost-effective solutions for modern transportation networks, steel highway grade separation bridges continue to play a critical role in improving mobility, enhancing safety, and extending infrastructure service life. The new guide provides practitioners with practical recommendations and technical insights to support informed decision-making throughout project development and delivery.
"The guide brings together current industry knowledge and practical experience to help owners, designers, and contractors advance successful bridge projects," said Mike Culmo. "Our goal was to create a resource that supports better decision-making and helps teams deliver long-term value for the communities they serve."
The publication further reflects CHA's commitment to advancing the transportation industry through technical leadership, innovation, and collaboration. By sharing lessons learned and best practices from projects across the country, CHA continues to help clients find effective solutions to complex infrastructure challenges.
