About this file
This is a Guardrail Installation Plan record drawing prepared by the County of San Diego Department of Public Works for a project near Valley Center Road (Project No. 39-B, R.S. No. C 052099). The plan was drawn by T. Huynh and B. Ehlers, recommended by K. Bradbury (Civil Engineer), and dated March 25, 2008. The project encompasses guardrail installation and related structural work at a location on Valley Center Road. The scope of work includes removing existing metal beam guardrail (MBGR), constructing flared terminal systems, in-line terminal systems, end anchor assemblies, buried post anchors, transition rails (Type WB), connection details per CalTrans Standard Plan 477K1, strengthened railing sections, and metal beam guard rail installation and repair. Additional work includes constructing alternative overside drains, resetting object markers and roadside signs, protecting in-place (PtP) elements, removing asphalt concrete dike and pavement, constructing headwalls, extending culverts, and placing imported borrow material.
The drawing set consists of three sheets presenting location maps, layout plans for multiple approach and departure locations, construction notes, and legends identifying proposed and existing MBGR installations and sign construction details. The plans show various guardrail configurations designated as Type II, Type IIE, Type IIH, and Type IIJ layouts with associated overside drain specifications. Cross-sectional details indicate traffic lane configurations with existing and proposed elements. The document serves as the technical specification for construction work and references CalTrans Standard Plan references (477K1, 477A1, 477E2, 477E5) for connection and construction details.
