October 22, 1987
We spoke on the telephone this summer about the proposed
highway through Logan Canyon. You subsequently asked for copies
of legislation that had changed Interstate design standards in
order to address environmental concerns. I've enclosed copies of
the two instances where an actual law was passed.
I also asked FHWA for examples where they had made
administrative changes in design standards for environmental
reasons. They gave me the following examples:
Projects where designs were down scoped including reduction
of lanes but not below 4 lanes:
-- 1-476 in Philadelphia
-- 1-279 in Pittsburgh
--1-676 in Philadelphia
--1-66 in Washington, D.C.
Projects where designs were revised to include cut and cover
requirements because of environmental reasons include:
-- 1-10 in Phoenix
-- 1-90 in Seattle
-- 1-696 in Detroit
-- 1-78 in New Jersey
I hope that this information is helpful and apologize that
it took so long. Jean Launer Staff Senate Environment & Public Works Committee
