The proximity of a proposed freeway to Lake Superior represented one of the most
critical challenges of the entire Interstate 35 corridor within the City of Duluth. The
freeway's alignment between downtown and lakefront areas demanded unique
design solutions to protect environmental resources, link major downtown land use
areas and improve pedestrian access to the long neglected lakefront.
A three acre, ten million dollar park structure over the freeway was the Landscape
Architect's design concept to eliminate negative impacts identified during a long
public involvement process. The urban area impacts included the following:
1 The freeway and placement of protective walls along the lakeshore would have
created visual, as well as, physical barriers between commercial/residential areas
and Lake Superior.
2 Freeway alignment would have eliminated any significant potential for lakefront
open space in the vicinity.
3 Severe weather conditions off Lake Superior would cause hazardous roadway icing.
4 Proximity of the highway to downtown and the lakefront would have created
severely negative impacts of noise, lighting, air quality and accessibility.
5 Long range community goals to unify and strengthen the core downtown would
have been forfeited.
Because citizens of Duluth and State/Federal Departments of Transportation
recognized these potential impacts, lead role opportunity was well defined for the
Project Landscape Architect. The design team included MnDOT administration
and staff, the City of Duluth and several consultant civil, structural, mechanical and
electrical engineers. The Landscape Architect's role was Urban Design Lead, and
included Conceptual through Final Design Services for architectural and site
components of Lake Place.
Defining the needs, and programming the extent and levels of improvement for the
facility were the initial Landscape Architect's challenge. This early conceptual work
and extensive project justification became basis to obtain Federal, State and City
funding commitments involving a wide-range of design opportunities…all focusing
on design solutions to integrate the highway and city in linking the public with Lake
Superior.
Lake Place incorporates two major elements. First, a wall was constructed between
the roadway and the lake. A covering deck was then built over the highway to
provide protection from Lake Superior over-spray and wind-driven debris. Second,
and most important, the deck of the protective structure was planned as a multipleuse
outdoor area in conjunction with the development of lakefront trail systems.
These multiple-use concepts for Lake Place and the Urban Highway Corridor have
created harmonious transportation, recreation, open space, and quality
environment far-exceeding visions of client-city-citizen expectations. It also resulted
in community reinvestment and renewal of once marginal lakefront property. This
unique oasis for travelers and residents not only protects, but becomes a Gateway
for the most valuable natural resource of the region ... "Lake Superior."
Design concepts insure that the freeway will not visually or physically separate the
lakeshore from the City. The two block long Lake Place park structure forms one of
four highway tunnels within the corridor. Although a "tunnel" in name, Lake Place
was envisioned as a pedestrian "bridge" connecting people and places; acceptance
has been enthusiastic as citizens could finally see, and physically reach their Lake.
A 580 ft. long ceramic tile Image Wall mural on the outside highway wall faces lake
level use areas. Consistent with community waterfront themes, this depicts historic
marine images and provides additional highlight for lakefront trail visitors. Lake
Place is continuing to accomplish one of its goals with new adjacent improvements,
development and attractions; easily a dozen adjacent downtown blocks will see
eventual renewal as direct result of this multiple-use highway improvement.
A comprehensive MnDOT/FHWA program, the Urban Interstate 35 resulted in
several individual multiple-use improvements with Lake Place as the focus. These
were designed as a system, and share continuity of design philosophy, design
vocabulary of materials, colors, textures, native vegetation, site lighting and subtle
messages of environmental awareness. Public acceptance is best illustrated by
observing response through public use and enjoyment of these rediscovered
resources; a recent comment to the Landscape Architect was, "…with these
improvements, there is a NEW SPIRIT in Duluth !"
The Downtown Duluth Interstate issues with their 20-year environmental stalemate
illustrates the crucial importance for Landscape Architects to state their case and
initiate leadership to attain" something better". Lake Place, and other highway
corridor multiple-use improvements are living examples that a larger context of
human and community opportunities exist, and need to be identified through
established inventory, analysis and solution procedures.
