Example Problems
Challenges with Current National Standards
- Standard is to close the sidewalk and detour peds
- Results in improper pedestrian movements
- Restricts safe access to businesses
- Adds sign clutter which reduces focus on regulatory signs
- Work zone signing can be confusing
- Work zone signing prone to incorrect installation
- Detour and work zone signing is mostly ignored
- Not truly in compliance with ADA
- Access not provided to locations along the closed sidewalk
- Sidewalk network is not always available
Example Problem #1
School children endangered by sidewalk closure
-
- No alternative detour route for children traveling to and from school
- Alternate alignment places children too close to traffic or on severe cross-slope
- Entire route closed for small sidewalk patching job
- Children on bikes moved into lane to pass work zone
- Vehicle avoided striking children by hard braking
- Not in compliance with federal and state law
- No feasible alternative prior to SpanPath
Example Problem #2
Sidewalk repairs along entire block
- No alternative detour route
- Alternate alignment places pedestrians too close to traffic or on severe cross-slope
- Entire block is closed
- Duration of sidewalk closure approximately 30 days
- Unsightly signing and barricades not addressing the pedestrian needs
- Not in compliance with federal law
- No feasible alternative prior to SpanPath
