1.4 Project Need
Improvement needs vary throughout the seven-mile study area and fall into one of five categories:
• Improve safety for all users.
• Improve mobility for all users.
• Address infrastructure deficiencies.
• Improve access and circulation.
• Improve modal connections and opportunities.

Situation
Lake Shore Drive is an essential Chicago artery with more than 150K vehicles per day
Roadway designed 100 years ago and unable to
handle traffic demand
Congestion, curves and potholes cause crashes and gridlock that have negative social and economic costs
Physically seperates City from its Lakefront
Negatively impacts viewsheds, environment and property values
On/off ramps create
dangerous interactions with Lakefront Trail users
High Usage and Congestion A Grey Divide

Opportunity to Elevate Chicago
Immerse Outer Drive in offshore two-level tunnel in shallow trench; eliminate weather impact from road conditions
Expand Outer Drive to 6-lanes each direction; upgrade access points to alieviate congestion and stoppage risks
Construct segments offsite at Port of Chicago; float into place. No disruption to the Drive while new one is prepared.
Create 1000s of jobs via PPP Private, State, Federal funding
Gain 80 acres of lakefront park and car-free Lakefront Trail
Cover tunnel with beach erosion-prevention technology
Lake Depth Immersed Tunnel Cross-Section
Transformative Outcome
Shallow depth and soft lakebed
are optimal for immersed tunnel
Protection layer
General fill
Locking fill Gravel bed

6-lanes on two-levels of stacked tunnel + corridors for light rail and/or bus rapid transit
NLSD-I capacity 2x greater than today; 300,000 cars a day without congestion
New ingress/egress access to or “under and past” Inner Drive eliminate bottlenecks
80 acres of parks and expanded auto-free Lakefront Trail for safe capacity increase

What?
An immersed tunnel is an underwater tunnel composed of segments made of steel or cast iron tubes lined with concrete using conventional shipbuilding techniques.
Immersed tunnels are used in conjunction with other forms of tunnel at their ends to continue the tunnel from near the water's edge to the at-grade on-land surface.
How?
1. The tunnel is made up of separate, prefabricated segments that are produced offsite and sealed at each end with bulkheads so that they can float like a boat.
2. In parallel to segment production, an underwater trench is dredged and graded along the tunnel’s planned route.
3. When a trench section and its specific segments are ready, the segments are floated to the appropriate location above the trench, then slowly sunk into place. Once in place, they are aligned and connected to the adjacent segment(s).
4. After a segment is connected, a water-tight seal is created between adjacent segments, the tunnel is emptied of water and the underwater trench is then backfilled and any necessary protection is installed.
5. Once the immersed tunnel is connected and sealed airtight from end to end, it is linked to its bored or above-ground access points. Once these connections are completed, then the roadway/infrastructure inside the tunnel can be constructed.
Where?
USA: New York City’s 63rd St. 4-bore rail tunnel; San Francisco’s TransBay subway rail tunnel; Oakland’s subway rail tunnel; Baltimore’s 4-tube Fort McHenry tunnel; Detroit-Windsor 2-lane auto tunnel; Boston’s Ted Williams 3-lane auto tunnel.
Global: Montreal, Denmark, Sweden, Netherlands, Germany, Sydney, UK, Japan.

TAG Holding’s proposed solution for evolving North Lake Shore Drive through the use
of a two-level, stacked offshore immersed tunnel meets and exceeds the defined
NLSD Project Needs for safety, mobility, addressing deficiencies, and improving
access, circulation and model connections and opportunities.
TAG’s solution resolves the myriad micro-problems with NLSD’s current design in one
fell swoop and strategically elevates Chicago by:
1. Eliminating a highway from its visible downtown Lakefront
2. Creating the space for profound Inner Drive and Lakefront Trail improvements
3. Increasing Lincoln Park’s area 7% with 80 new acres.
By making use of existing tunnel technology in an innovative manner, TAG’s solution
elevates Chicago to a level of global leadership in multi-modal transportation
infrastructure. Leveraging innovative infrastructure finance for the $2.2 billion PPP
budget provides the capital needed to invest in job creation and preparing Chicago
and the metro region for a more sustainable future. And the pay-per-use toll model
via I-Pass enables a sub-14 year project payback period.
If we are to follow Daniel Burnham and “make no little plans”, then TAG’s immersed
tunnel solution should be selected as the preferred alternative and implemented
over two years by 2020. Thank you for your time and consideration.
