COMMON FEATURES
Reconstructed mainline, service drives andbridges
Improvemen ts to southbound ramps toMonroe/Lafayette and Larned/East Jefferson (asproposed in previous MDOT studies)
Improvements at Gratiot /Madison/St. Antoineintersection
A riverfront connection from East Jeffersonto Atwater with bike lanes and pedestrianimprovements
Bike lanes along northbound and southboundservice drives
Landscaped freeway slopes with storm watermanagement
Pedestrian improvements along service drivesand on reconstructed bridges
No residual land created for potential reuse
Reconstructed mainline, service drives andbridges
Improvement s to southbound ramps atMonroe/Lafayette and Larned/East Jefferson (asproposed in previous MDOT studies)
ESTIMATED TOTAL COST: $60-70M
All alternatives were developed withconsideration of future peak traffic demands
Each alternative was developed with a CompleteStreets approach, balancing the needs of alltransportation modes
The new growth and development that isoccurring and planned to occur was integratedinto the plans
Designed to improve public safety, minimizeimpacts to environmental resources andenhance the economic vitality of the corridor
Reconstructed freeway shifted to the west(downtown side)
New retaining wall for service drive in order tonarrow freeway width
Improvemen ts to southbound off-ramp atMonroe/Lafayette
Freeway transitions to surface street at Larnedto eliminate the Jefferson curve and better servethe riverfront and south end of the corridor
New riverfront connection from Jefferson toAtwater with bike lanes and shared use path.
Northbound service drive converted to a two-way local street with bike lanes
Shared use (bike/walk) path with storm watermanagement between the new local street andthe freeway.
Pedestrian improvements along service drives,ramps and new at-grade streets
Potential property for reuse along the south sideof Jefferson Avenue (approximately 2 acres)
Freeway transitions to surface street at Clinton;reconstructed as a surface roadway southerly;Alignment shifted to the east (neighborhoodside)
Southbound service drive eliminated; function
replaced by new surface street
Riverfront connection from Jefferson Ave. toAtwater St. with shared use path
Pedestrian improvements along new boulevardstreets
Shared-use path along the east, neighborhoodside
Potential property for reuse along the west sideof the I-375 corridor and south side of JeffersonAvenue (approximately 9.3 acres)
Freeway transitions to a surface street at Clintonwhere it is reconstructed as a boulevard,replacing the southbound service drive;Alignment shifted to the west (downtown) side
Northbound service drive converted to a two-
way local street with bike lanes
Riverfront connection from East Jefferson toAtwater with bike lanes
Pedestrian improvements along new boulevard
Potential property for reuse along east side ofcorridor between boulevard and local street,and along the south side of East Jefferson(approximately 8.5 acres)
Freeway replaced with two one-way roadwaysbeginning at Clinton and shifted to the servicedrive alignments
Temporary or permanent conversion of below-grade space to multi-use trail
Riverfront connection from East Jefferson toAtwater with shared use path
Pedestrian improvements along new surfacestreet
Buffered bike lanes on one-way roadways
Potential property for reuse between thenorthbound and southbound roadways,and on the south side of Jefferson Avenue(apporoximately 11.6 acres)
