Current Study


Led by Hennepin County but developed in partnership with City of
Minneapolis,
MnDOT
, and Metro Transit.


Project Limits


31

Project Costs


$150 Million for Lake Street Access Project


$63 Million to $100 Million for Chapter 152 project (Braid Bridge and NB
Flyover)


Project Scope:

Reliable connection to the Mid

Town
Greenway


Determine configuration of the SB Braid
Bridge and NB flyover.


These elements developed to a 30% design
Level


Vision for I
-
35W provides for an On
-
Line transit
facility from Lakeville to Downtown Minneapolis


UPA projects on I
-
35W advanced this vision


Remaining elements to complete the vision of an
On
-
Line transit facility on I
-
35W


Lake Street Access Study developing the concept for an
On

Line Transit Station at Lake Street


I

494/I
-
35W Study Developing the concept for an On
-
Line Transit Station at American Boulevard


Met Transit submitting I
-
35W Corridor into Small
Starts Program to identify funding for remaining
elements on I
-
35W.


Southbound Exit Ramp to Lake Street


Requires Auxiliary lane on SB I
-
35W from I
-
94
commons.


Northbound Entrance Ramp from Lake Street


City of Minneapolis Council recently approved a
resolution to remove this access from current project


Project will not construct this access, but will not
prohibit the access from being constructed in the future.


Estimated Cost of this ramp is $37 Million, reducing the
project estimated cost to $113 Million


Northbound Exit Ramp to 28
th

Street


Provides direct access to two major traffic generators
(Allina Health Group and Wells Fargo)


Reduces congestion on 31
st

Street and Lake Street


Hennepin County has reconstructed Lake
Street from
Blaisdell

Avenue to the west and
from 5
th

Avenue to the east.


Upon the determination of the final
configuration of Lake Street between
Blaisdell

Avenue and 5
th

Avenue, Hennepin County will
program a project to complete the
reconstruction of Lake Street.


The Mid
-
Town Greenway is a parallel route to
Lake Street that provides a multi
-
modal facility
for bikes and
pedes


The Greenway Coalition is studying this corridor
for the potential use of street cars that would
connect the Hiawatha Light Rail Transit Corridor
with the future Southwest Light Rail Transit
Corridor.


The Lake Street Access Study needs to provide a
quality connection between the Greenway and the
On
-
Line Transit Station at Lake Street.


Mid
-
Town Greenway Connection

Conceptual Visualization


Mid
-
Town Greenway Connection


Currently braids over NB TH 65 and merges with
SB TH 65 on the left.


Proposed to be re
-
aligned to braid over NB and
SB TH 65 and merge on the right.


This will allow for improved operations of SB I
-
35W with
respect to the traffic exiting at Lake Street


This will also enhance transit within the I
-
35W corridor
by allowing for the development of a managed facility on
SB TH 65 out of Downtown Minneapolis.


This is being developed with the Lake Street
Access Study, but will be delivered as a
MnDOT

project in FY 2018.


Ramp currently enters WB I
-
94 on right side


This study will determine the appropriate
treatment of this ramp.


Right hand entrance as it is today


Left hand entrance


This is being
developed
with the Lake Street
Access Study, but will be delivered as a
MnDOT

project in FY 2018.


An issue that will be worked through is the
determination of maintaining the 4
th

Avenue
entrance ramp to WB I
-
94.

Project is currently un
-
funded by the four partner agencies


City and County looking to let project as a whole in 2014 to 2015
timeframe


MnDOT

has $25 Million commitment from previous studies, but this is not
identified in our program


The Lake Street Access Project had approximately $9 Million of 2004 HPP
Funding that was affected by the Federal Government
Recission
:


$1.5 Million will be used for additional studies for the Lake Street Access
Project


$7.5 Million re
-
distributed, but the commitment will be honored in our
program.


Metro Transit is seeking funding via the FTA Small Starts program that
would cover the transit elements of the project.


The political pressure to identify funding for the project will
escalate as the development of that project moves closer to the
30% design level. This pressure will most likely be pointed to
MnDOT

and Metro Transit as the majority of the project elements
will either be transit related or freeway related.



Project currently programmed in our Highway
Improvement Plan for $63 Million


The determination of the appropriate location
for the Northbound Flyover Bridge will impact
the project scope and cost.


The maintenance of the many elements that
make up the transit access project will need
to be negotiated:


Bridge Maintenance


The Lake Street Bridges will be longer than would be
required to bridge Lake Street to facilitate the transit
station.

The Transit Station Elements


I
-
35W Corridor was constructed in 1967


The
inplace

pavement is Continuously
Reinforced Concrete Pavement Between 42
nd

Street and I
-
94 Commons.


The current preservation cycle for this
corridor is a mill and overlay every 5 to 7
years.


A longer term solution for the pavement
would extend the project limits, but also
impact the project scope and cost.


The I
-
35W corridor has drainage tunnels to carry the
runoff from I
-
35W as well as Minneapolis.


MnDOT

and the City of Minneapolis have a maintenance
agreement to identify maintenance responsibility, but
funding for the maintenance has not been identified at this
point.


The tunnels currently pressurize during heavy rain events.


The solution to this is to construct a parallel tunnel and split the
flow. The estimated cost of this improvement is $70 Million


The Lake Street Study is determining how much work could be
done without adding additional flow to the tunnels, but this issue
needs to be vetted with further study.


A risk to the I
-
35W projects is that we can’t treat the additional
water and the parallel tunnel would be required as part of the
proejct
.
