Philadelphia, Pennsylvania, United States
Decades of continuous use have taken a toll on I- 95 in Philadelphia, Pa., and
its numerous bridges. To ensure that the region’s primary north-south artery
meets the demands of commerce and commuters well into the future, the
Pennsylvania Department of Transportation is in the midst of a long-term,
multiphase, $350-million initiative to improve and rebuild a portion of I- 95.
Nave Newell used 3D laser scanning, MicroStation, and Bentley Cloud Worx
to survey the existing structures during the project’s preliminary engineering
phase. The highly detailed models depicted roadway surfaces, paving edges,
gutterlines, elevations, grades, and profiles to be utilized in the design of
roadway, structure, and ramp improvements. The 3D PDFs helped the designers
understand existing spatial conditions and determine the best approach.

Park and Ride Ramp Bridges
Tel Aviv, Israel
The $10 million Park-and-Ride facility at the east entrance to Tel Aviv on
Highway 1 aims to reduce traffic jams, speed up traffic, and reduce pollution.
The traffic scheme for the facility includes a group of ramp bridges with
extremely sharp curves. Curvature radii for the two bridges are 56 meters and
27 meters measured from the centerline of the ramp deck.
Shamir Posner Brown carried out the conceptual and detailed design of the
bridges using RM Bridge. The package proved to be efficient for precise modeling
of the demanding bridge geometries with sharp curvatures, changing slopes, and
superelevations. The designers took into account each individual cable alignment
and profile to create a 3D model for the various construction stages.
