Transportation Engineering

J3 provides the full range of services necessary to support the planning and design of safe and functional roadway networks.  Our design and construction management expertise ranges from private streets, alleys, local, collector and arterial roadways.   Additionally, work on County Roads, DOT Highways, Roundabouts, Maintenance of Traffic Plans and Regional and Sub-Regional Pedestrian network have been completed in multiple cities, counties and DOT regions. 

Our projects benefit from an in-depth understanding of drainage, utilities, master plans and general civil design.  They are completed in accordance with local criteria, AASHTO’s Policy on Geometric Design of Highways and Streets and the Manual of Uniform Traffic Control Devices (MUTCD).
