Multimodal Transportation Engineering Services
Safe and Connected Streets for Every Mode
Sanbell’s multimodal transportation engineering blends safety, accessibility, and efficiency to create streets and corridors where every traveler belongs, whether on foot, bike, bus, or behind the wheel. Our expertise spans multimodal transportation planning, pedestrian and bicycle infrastructure engineering, transit-oriented design, and safe streets solutions that strengthen connections within and between communities delivering context-sensitive designs that respect local character while meeting modern mobility needs wherever you are.
What We Do: Comprehensive Multimodal Design Services
Our engineers plan and design systems that give people safe, reliable options for how they travel, recreate, and stay connected. We integrate complete streets design, ADA-compliant pedestrian crossings, and safe streets engineering into corridors that balance mobility, safety, and community goals. From trail network and shared-use path planning to transit-oriented transportation design, our solutions are built for everyday use, long-term performance, and above all? The people who use them.
