Full Description

The Contra Costa County Public Works Department (County) proposes to remove sub-standard Metal Beam Guardrails (MBGR) and end treatments and replace them with the current Caltrans standard Midwest Guardrail System (MGS) guardrails and end treatments at the locations identified above. Approximately 52 existing guardrails will be upgraded, and one new guardrail will be installed. The construction process will include removal and replacement of the existing guardrails, end treatments and associated posts, and relocation of several guardrail posts near end treatments with grading as needed. Ground disturbance and excavations up to eight feet are anticipated. Approximately four trees may be removed, and vegetation and tree trimming may be necessary. All applicable regulatory permits will be obtained before construction. Real Property transactions and utility relocations may be necessary. Construction is currently anticipated to occur in summer 2026 and will take approximately two months to complete. Temporary traffic controls will be implemented during construction activities and may include short duration lane closures, including one-way traffic control, resulting in short traffic delays. Emergency vehicles will have access at all times. Appropriate best management practices, including but not limited to measures for stormwater control (e.g., storm drain inlet protection) will be implemented during construction.
