ReopeningOur Front Door


2/21

In 1964 construction of I-70 closed the new front doorof St. Louis before it was even finished.


3/21

I-70 created a 1.5 mile long physical and psychological barrier,closing St. Louis from its historic front door: the riverfront.


4/21

Spaces under the elevated portion of I-70 are dismal at best& the maze of roadways at grade is confusing and disjointed.


5/21

The depressed section resembles a gapingwound in the landscape of the St. Louis.


6/21

Between the elevated and depressed sections, I-70 completelyseparates the Arch grounds from Downtown St. Louis.


7/21

It is time we reopen

our front door

So what would all of this cost?

The new Highway 40/64 cost $524 million for 10.5 miles

including 20 new bridge structures, or about $50 million

per mile.

The New Memorial Drive would run 1.4 miles from the

Poplar Street Bridge to Cass Avenue, and would involve

mostly demolition, fill and paving at grade. There wouldbe no new bridge structures included in the project. If a

worst case cost equaling Highway 40 is used this would

be about $70 million.


21/21

What are the alternatives?

The Lid concept, whichwould actually be a tunnel

would cost $87 million and

would only span 3 blocks,

leaving the depressed &

elevated lanes as well as the

transition barriers to the

north and south.

Comparing $87 million for a 3 block tunnel with $70 million

for the 1.4 mile New Memorial Drive, the New Memorial

Drive is a much better value.
