As the Prime Consultant, provided civil engineering services for this project consisting of providing additional through capacity for Broadway Avenue from NY 27 (Sunrise Highway) to NY 454 (Veterans Memorial Highway). Subsequent to performing site observations and conducting interviews with local residents it was determined that additional through capacity was needed. The other alternative considered was to modify the green time allocation at the intersection of Broadway Avenue with NY 454 in order to give more green time to Broadway Avenue. This alternative was not considered reasonable since it would adversely affect NY 454 which is the primary roadway at the intersection. These findings were summarized in a Design Report.
Then detailed design plans were developed which incorporated widening on the west side of Broadway Avenue. The proposed plans included the design of a new traffic signal at the intersection of Church Street and Broadway and the modification of the traffic signal at the intersection of Broadway Avenue and NY 454. Acquisition maps were developed for the widening areas. The proposed plans were submitted to NYSDOT for review and their comments were incorporated into the project. Also included in this project was the development of specifications, cost estimate and specific construction details.
