Route 246 CAPM and Robinson Bridge
Project Description
This project is on State Route 246 in Santa Barbara County in and near the city of Lompoc, from State Route 1 to 0.047 mile east of the Domingos Road intersection. The project proposes to replace the Santa Ynez River Bridge (Bridge Number 51-0128) at post mile 9.8, preserve 21.7 lane miles of flexible Class 2 pavement using Capital Preventive Maintenance strategies, place 0.20 foot of Rubberized Hot Mix Asphalt overlay, rehabilitate culverts, upgrade sign panels, upgrade existing curb ramps to be Americans with Disabilities Act compliant, and upgrade guardrails to Manual for Assessing Safety Hardware standards.
Project Benefits
Purpose
The purpose of this project is to preserve and extend the life of the existing pavement, rehabilitate pavement and culverts, upgrade guardrails to Manual for Assessing Safety Hardware standards, upgrade sign panels, and replace the Santa Ynez River Bridge to accommodate pedestrians, bicyclists, and flooding.
Need
The Pavement Condition Summary Report documented that the pavement condition within the project limits is deteriorating. Continued deterioration of the roadway could result in roadway failure.
- Various culverts exhibit scour, sediment buildup, and shape loss; continued culvert deterioration could lead to roadway failure.
- Sections of guardrails within the project limits do not meet Manual for Assessing Safety Hardware standards; outdated guardrails will not react to collisions in the same way as updated standard guardrails.
- Sign panels are due for replacement or upgrade.
- The Santa Ynez River Bridge was built in 1939. Federal Emergency Management Agency flood maps indicate that a 100-year flood would overtop the bridge. The Bridge Inspection Report, dated March 6, 2017, indicates the bridge is scour critical, and a work recommendation, dated August 30, 2016, calls for replacement due to scour conditions and bridge age. The bridge's width does not safely accommodate pedestrians or bicyclists. A pedestrian path was identified in the Complete Streets performance objectives.
