With commuter traffic growing and rush hour extending to nearly all-day, today’s streets need to withstand constant usage, as well as harsh weather conditions. Our engineers design and provide services for roadways in both metropolitan and suburban areas. As one of the top 25 highway designers in the country, we are involved in some of the most expansive highway development programs nationwide. Our assignments include road relocations, toll plazas, drainage and storm water management, and noise impact evaluation. Our experienced staff possesses extensive engineering experience to undertake highway projects of varying scope and complexity. STV’s vast project portfolio allows various government agencies, as well as clients, to trust in our design and engineering skills for unique and cost-effective solutions to the most challenging highway development issues.
