Alternatives considered

Several alternatives were considered to address safety and operational concerns westbound on I-94/I-794. View exhibit.

Alternative 1: Channelization

• Reinforce current pavement marking and configuration on I-794
• Prevent queue jumping to reduce friction and turbulence through the Marquette Interchange
• Does not show any significant operational improvements

Alternative 2: Original Marquette Interchange Configuration

• Restore two lanes on I-794
• Re-establish forced merge of I-94 and I-43
• Presents safety concerns due to forced merge
• Does not address poor traffic operations and peak hour congestion

Alternative 3: Inside Merge

• Maintain single lane on I-794
• Merge 11^th Street on-ramp with I-94 system ramp
• Presents safety concerns due to left-hand forced merge within the system interchange
• Does not show any significant operational improvements

Alternative 4: I-794 Left Lane Drop

• Restore two lanes on I-794
• Drop and merge left lane at approximately 25^th Street
• Presents safety concerns due to left-hand forced merge occurring simultaneously with right lane drop
• Shows some operational improvements

Alternative 5: 25^th Street Gore Relocation

• Restore two lanes on I-794
• Re-establish forced merge of I-94 and I-43
• Relocate 25^th Street gore to system ramp merge to prevent I-794 traffic from exiting at 25^th Street
• Presents safety concerns due to forced merge
• Shows some operational improvements

Alternative 6: Auxiliary Lane/Preferred Alternative

• Restore two lanes on I-794
• Maintain single lanes for I-94 and I-43
• Extend auxiliary lane from 25^th Street to 35^th Street to reduce merging and weaving on I-94
• Shows significant operational improvements
