Study Overview
5
Purpose of the study is to focus on:
• Traffic Safety
• Operational Needs
• Directional Weekday (Monday – Friday) Peak Period Congestion
• Infrastructure Condition
Goal is to: Develop Safe, Efficient, Sustainable Transportation Improvements to assure that the corridor will meet current and future
highway operations using state-of-the-art traffic control measures along with improved infrastructure.

Study Overview
6
Need is to focus on:
• Economic feasibility regarding restricted funding;
• Pavement condition;
• Directional weekday (Monday – Friday) peak period congestion;
• On-ramps that are short to adequately accelerate and merge into
traffic;
• Traffic operations at M-36, Silver Lake and I-96 interchanges;
• High crash segments throughout the corridor;
• Incident management areas to safely clear and investigate accidents; and
• Road and bridge maintenance.

Study Overview
7
The Study includes:
• Road and bridge scoping to extend the US-23 Flex Route to I-96;
• Recommended alternatives at the M-36 and Silver Lake Road interchanges;
• Environmental Analysis that identifies potential environmental impact locations; and,
• NEPA documentation

Existing and Future Traffic Conditions
8
Congestion (2020) –
• AM – Southbound US-23 near the
eastbound I-96 on-ramp as well as the
Silver Lake Road interchange.
• PM – Northbound where the flex lane
currently ends north of 8 Mile Road, as
well as near Lee Road and the I-96
ramps.

Existing Safety Conditions
9
• Analyzed crashes from 2015 - 2019• Highest percentage of crashes near the
interchange areas • 99 crashes per year in southbound direction• 228 crashes per year in northbound
direction • High number of rear-end crashes due to
rush hour congestion• Short acceleration and deceleration lanes

Existing Road and Bridge Conditions
10
• Acceleration and deceleration lanes are short• Shoulders are narrow • Pavement condition is fair to poor (north of
Silver Lake Road)• Bridges are in fair condition
• Study will document fix type
