PROPOSED ACTION |
|
Description |
The toll plaza would be split into two plazas
located side by side. The Thruway ramps would be reconstructed
south of the Thruway mainline and the I-890 ramps
reconstructed to form a diamond interchange at Curry Road. |
The toll plaza would be split into two plazas
located side by side. The Thruway WB entrance ramp would be
reconstructed and the I-890 ramps reconstructed north of Curry
Road to eliminate the existing weave on I-890. |
The toll plaza would be realigned to remove the
existing curve at the eastern end of I-890. The Thruway WB
entrance ramp would be reconstructed and the I-890 ramps
reconstructed north of Curry Road to eliminate the existing
weave on I-890. |
