Reconstruction of New Rochelle Toll Barrier (I-95)

DESCRIPTION:
The project includes a study of design alternatives for the Toll Plaza, including the realignment of I-95 to facilitate the use of “highway speed” E-ZPass at the toll barrier. Work consists of design and ROW survey and mapping; pavement evaluation; development of a micro-simula- tion model for traffic flow; environmental studies for air, noise, asbestos assessment and visual impact assessment; and development of the Design Approval Document. BLA will provide Phases I-IV for the Final Design.

Bruckner Expressway Reconstruction

DESCRIPTION:
This project includes the final signing design for the Bruckner Expressway from the Throgs Neck Expressway to Gun Hill Road. Final signing includes special design of span type and cantilever type overhead sign structures. It also involves preparing design alternatives for a fourth lane extension of the northbound New England Thruway (I-95) north of the Westchester Avenue on Ramp for the Bruckner Expressway, from Pelham Parkway to Gun Hill Road.

Yonkers Toll Barrier Studies (I-87)

DESCRIPTION:
BLA was retained to perform a study of various design alternatives for the Yonkers Toll Plaza to facilitate the use of highway speed E-ZPass at the toll barrier. Tasks included the determination of 85th percentile operating speeds, speed delay estimates, traffic counts, turning move- ments, queuing analyses, weaving analyses and LOS analy- ses. A null alternative and two build alternatives were studied. Conceptual plans, a plaza rendering and con- struction estimate for each alternative were developed.
