Public and Private Roadway Design

Designing Safe, Efficient, and Compliant Roadway Systems

Public and private roadway design is essential for creating safe, functional, and well-connected transportation networks. From local streets to private access drives, effective roadway design ensures efficient traffic flow, accessibility, and compliance with local and state standards. Our designs balance safety, durability, and cost-efficiency to meet the needs of both public agencies and private developers.

Benefits

Create Safe and Functional Roadways

Our designs focus on prioritizing safety, incorporating proper lane widths, signage, sight distances, and pedestrian access features.

Address Compliance With Local and State Regulations

Our roadway designs are built to align with VDOT standards, municipal requirements, and ADA accessibility guidelines to support smooth approvals.

Support Long-Term Durability and Efficiency

Engineered for longevity, our roadway designs incorporate proper drainage, pavement structures, and traffic management features.

What to Expect

The roadway design process follows a structured approach to create safe, efficient, and compliant transportation systems. Here’s what to expect:

* Every project is unique! Exact steps and services will vary.

1. Site Analysis and Traffic Assessment 

We evaluate site conditions, traffic patterns, and projected volumes to determine roadway alignment, capacity, and safety requirements.  


2. Horizontal and Vertical Alignments  

We design roadway layouts, including curves, intersections, and profiles, to optimize safety, efficiency, and accessibility.  


3. Roadway Cross-Sections and Pavement Design  

Detailed cross-sections and pavement structures are designed to ensure durability and compliance with local standards.  


4. Intersection and Traffic Control Design  

We incorporate traffic control elements such as signage, striping, signals, and roundabouts to promote safe traffic flow.  


5. Drainage and Stormwater Integration  

Our designs include roadside ditches, culverts, and stormwater systems to manage runoff and prevent roadway flooding.  


6. ADA-Compliant Pedestrian and Bicycle Facilities  

Sidewalks, crosswalks, and bike lanes are designed to meet accessibility standards and promote multimodal transportation.  


7. Maintenance of Traffic (MOT) Plans  

We develop MOT plans to ensure safe and efficient traffic flow during construction phases.  


8. Permitting and Coordination With Agencies  

We coordinate with agencies like VDOT and local municipalities to obtain necessary permits and approvals.
