State Route 88 Roadway Improvements
Project Description
This Capital Preventive Maintenance (CAPM) project proposes roadway improvements along State Route (SR) 88 in Amador County between the west SR 124 Junction, Post Mile (PM) 5.5, and the north SR 49 Junction PM 14.3. The scope of work includes cold planing and overlaying existing pavement, replace asphalt concrete surfacing and dig-outs at spot locations to repair localized failures, shoulder backing, upgrading roadside signs, replacing three culverts, and 16 down drains and upgrading existing metal beam guardrail to the Midwest Guardrail System.
Project Benefits
Purpose
The purpose of the project is to preserve and extend the service life of the existing pavement and improve its ride quality, prevent potential flooding or undermining of the roadway and bring existing metal beam guardrails to current standards.
Need
The project is needed to address the gradual deterioration of existing pavement and culverts, poor highway ride quality, and the nonstandard metal beam guardrail.
