ADOT Design

 

SR 303: Waddell Rd to Mountain View Blvd. Surprise, AZ

 

As a project engineer Chris designed pavement marking, roadway signing, traffic control, traffic signal, interconnect and roadway lighting plans. The designs included custom sign formats and sign structure details. This project along with an adjacent segment ‘kicked-off’ the upgrade of SR 303L from a two-lane roadway to a full freeway cross section. Design elements developed on the first two segments set the tone for the future of the SR 303L corridor. Chris also lead internal efforts on post design including answering RFI’s and shop drawing review.

As lead traffic engineer, Chris Williams was responsible for the roadway signing and pavement marking designs.
