I-17 and Pioneer Road Interchange Improvements
|
YSMA was tasked to connect Gavilan Peak Parkway at the Pioneer Road Traffic Interchange on I-17.
Through Traffic Modeling, we demonstrated to ADOT and FHWA that the proposed connection will not create traffic backups on the off ramps to adversely impact the I-17 mainline traffic. As a result, FHWA did not require a Change of Access report. YSMA supplemented MCDOT in-house engineering team with the design. By taking into consideration the terrain constraints presented by the adjacent hill, we shifted the alignment of Gavilan Peak Parkway away from I-17 to create enough storage along the connector. YSMA coordinated approvals through FHWA, ADOT, and State Land Department. |
