Fort Drum Connector (I- 81 to US 11)
Pamelia and Le Ray, New York, United States
were being prepared. Views of the three feasible proposed alternatives were
depicted, as well as a visualization of the single-point urban interchange at
the west end of the project.
the new york State Department of transportation (nySDOt) is planning a
new four-lane connector between I- 81 and US Route 11 in northern New York
to improve access to the Fort Drum U.S. Army Base. Designed to serve as
an interstate facility with fully controlled access, this project is designated
as a federal high-priority SAFE TEA-LU project of strategic importance on
a statewide and national level. The high-profile project will alleviate traffic
congestion affecting the towns of Pamelia and Le Ray in Jefferson County as
well as provide a redundant military route to Fort Drum.
N YSDOT made an early commitment to make public involvement a priority.
The project team needed to communicate three design options and their
impact on the surrounding areas to all stakeholders. Selection of the
preferred alternative had to take place in a timely fashion as part of the
alternative selection process so this significant project could progress. At the
production level, constantly changing roadway alignments and digital terrain
models presented a challenge while visualizations of possible alignments
MicroStation, InRoads, and Project Wise allowed Lochner to work with
N YSDOT virtually. Visualizations were employed to show how the project
would look post-construction, and 3D MicroStation design files were created
that contained a gridded representation of both the existing and proposed
digital terrain models of the roadways. Aerial photos were then photo-
matched with these design files as the basis for photorealistic visualization.
Being able to show how the new connector would look in an area where no
roadway currently exists saved time in the alternative selection process.
Also, being able to describe the single-point urban interchange in a way that
the traveling public can envision was a tangible benefit.
