10th Street Corridor Overview
Downtown viaducts over the existing rail yard and
river.
Signal spacing not ideal to maximize traffic flow.
10th Street Corridor Overview
10th and Cliff intersection improvements in 2010, reconstruction due to significant crash
problems and need for capacity.
10th Street Corridor Overview
Multiple driveways and side streets affect corridor
progression.
10th Street Corridor Overview
Access from side streets difficult and impedes travel
speeds along Corridor
10th Street Corridor Overview
Interchange crashes typically at off ramps due to ramp queuing; lengthening
off ramp south of the interchange has helped mitigate this issue.
Distance between Cleveland Avenue & I-229 causes congestion due to
overlapping traffic backups; crash rates higher than normal at this location.
Single point intersection projected to be at capacity by 2035.
10th Street Corridor Overview
Cleveland Avenue expansion recommended between 12th Street and
Rice Street in 2008 study.
10th Street & Cleveland Avenue intersection projected to be over
capacity by 2035.
10th Street Corridor Overview
Numerous driveways along 10th Street impacts traffic flow and increases
potential for conflicts.
Adding lanes to 10th Street would be difficult due to adjacent businesses.
10th Street Corridor Overview
Intersection reconstructed in 2014 with dual left turn lanes and right turn lanes to address high
crash rates (48 crashes in 4 year period).
Connection to 12th Street in close proximity to Sycamore Avenue making it difficult to
enter/exit 10th Street.
