Bascule Bridges
Oregon St. over Sturgeon Bay
Sturgeon Bay, WI
Vinod was the Project Structural Engineer for design of this new bridge crossing the ship canal in Sturgeon Bay. The overall bridge is approximately 1060' long consisting of a double-leaf movable (rolling lift) bridge with a 200' wide navigation channel, 5 continuous PPC I-beam spans to the west and three continuous PPC I-beam spans to the east. The bridge cross-section consists of two 12 feet wide lanes, flanked with 6 feet wide shared shoulder/bike lane and 6 feet wide raised sidewalk on either side for a total width of 50 feet.

8th St. over Scheboygan River
Scheboygan, WI
Vinod was the Project Structural Engineer for this new bridge, which is a single-leaf fully unbalanced span operated by an industrial scale hydraulic fluid-power system and controlled by a triple-redundant state-of-the-art touch screen Programmable Logic Controller (PLC) Computer System. This new bascule design and the system was awarded a patent by the United States Patent Office. This project was located in an USEPA Superfund Site. Consequently, the project also included development of specific construction requirements to minimize river dredging and disturbance to the river sediments.

Michigan St. over Sturgeon Bay
Sturgeon Bay, WI
Vinod was the Project Manager for the preliminary study to rehabilitate or replace the 1,400-foot-long Michigan Street Bridge, which provides the crossing of Business 42/57 over the Sturgeon Bay Ship Canal and the approach roadways leading to the crossing. Several alternates with different route locations and different bridge types and sizes including rehabbing the existing bridge and building a new parallel bridge were studied.
Vinod then managed the Final Design and preparation of the PS&E package for the rehabilitation and repainting of the bridge.
Grand Ave. over Chicago River
Chicago, IL
Originally constructed in 1913, this bridge is a double leaf, trunnion type bascule bridge. It consists of one movable span with trunnion to trunnion distance of 189 ft and deck width of 60 feet.
​
Vinod was P.M. for the Preliminary Study and Engineering for the rehabilitation of the bridge, including in-depth inspections of the bridge and the bridge houses. This included structural inspection of the bridge and house structures, and the mechanical and electrical inspections of operating machinery and electrical/control systems.
​
Structural analysis and load rating of all the structural members were performed for their inspected condition to identify the need for strengthening and rehabilitation. Vinod's team prepared all preliminary documents including BCR, PDR and TS&L Plans.
Pedestrian Trail over Little Chute Canal
Little Chute, WI
Vinod was Project Structural Engineer for this new movable bridge across the Little Chute Canal and Fox River lock system leading to the Village’s Island Park. The unique Holland-style single leaf pedestrian lift bridge provides access to the island while also accommodating canal navigation. The main span of the bridge is 43 feet crossing a 35.5-foot-wide channel.
The movable span consists of a heel trunnion bascule leaf balanced via an overhead counterweight. The balance arm supporting the counterweight is connected to the bascule leaf by a pair of hangers near the tip of the leaf and is supported on overhung trunnions at the top of a pair of pylons.
