ASCE Sacramento
“Transportation Project of the Year”
2011
Shasta View Dr. & Old Alturas Rd.
Redding, CA
OVERVIEW
The development of a new elementary school resulted in the need for a new road connection on a two-lane city arterial in Redding, California. A feasibility analysis determined that a modern roundabout would provide better traffic operations than a signal, and handle the extreme traffic volume variation associated with a school better than a signal. Based on this analysis, the City of Redding selected this new intersection for its first modern roundabout.
SUMMARY
Acting as a sub-consultant to Omni-Means, MTJ Roundabout Engineering provided the operational analysis, final horizontal design, and QA/QC through final engineering for this intersection.
The roundabout opened as a single-lane design, but easily converts to a dual-lane entry from two legs if and when traffic volumes warrant capacity expansion.
HIGHLIGHTS
- New elementary school safety priority
- Accommodates traffic volume variation
- City’s first modern roundabout
- Convertible to dual-entry when traffic volumes warrant capacity expansion
