Grand Avenue Recommended Layout
Right of Way usage:
- Curb-to-curb width narrowed from 55 feet to 48 feet (7-foot roadway width reduction)
- Left turn lane remains at 10 feet
- Travel lanes narrowed from 13 feet to 11 feet
- Parking lanes narrowed from 10 feet to 8 feet
- Total non-vehicle space widened from 24 feet to 32 feet
- Sidewalks remain at 6 feet in residential areas, 8 feet in commercial areas
- Boulevards widened from 6 feet to 10 feet in residential areas, 8 feet in commercial areas
- In commercial areas with paved boulevard space, sidewalk space widened from 12 feet to 16 feet
Intersections:
At unsignalized intersections:
- Bumpouts installed at each non-signalized intersection narrowing crossing distance from 55 feet to 36 feet.
At Fairview Avenue:
- Bumpouts are proposed to be installed at each intersection quadrant, narrowing crossing distance to 36 feet.
At Cambridge Street:
Between Macalester Street and Snelling Avenue:
- The block segment will feature a unique layout which will be carried forward from a previous project done in coordination with Macalester College and Public Works in 2008. This project constructed the center median and established the current layout. The reconstruction will narrow the street width to be in line with the other segments of Grand Avenue but will maintain the existing layout between the crossing points. Rendering of the raised crossings.
- Grand Ave block segment between the east and west mid-block crossings:
- Sidewalk width: 8 feet
- Boulevard width: 14 feet
- Roadway width: 36 feet
- Through-lanes: 14 feet
- Center median: 8 feet
- Mid-block crossings through this section will be consolidated down to two from the existing three points. These crossings will be improved to legal crossings with signage, marking and be raised in order to maximize accessibility and traffic calming through the college campus.
