Lane Closure Alert: Modjeska Grade Road (May 2-3, 2023)

Lane Closure Modjeska Grade Road

Modjeska Grade Road

Assessments for Future Improvements Project, Will Require Lane Closures Over Two-Day Period


In preparation of a future project, OC Public Works will be assessing underground conditions, which will require temporary lane closures.

Work will include drilling six, 10-inch diameter holes with depths ranging from approximately 5 to 20 feet deep. The purpose is to assess underground conditions in preparation for a future roadway and drainage improvement project. Drilling activity at each location will last approximately 2 - 4 hours.

LANE CLOSURES: These activities will require temporary lane closures and brief traffic stops. Flag personnel will be on-site to direct drivers. These lane closures will only occur over a two-day period.

About the future project: We are planning future improvements to Modjeska Grade Road to address the recurring stormwater drainage and roadway safety issues, including: Pavement rehabilitation, installation of guardrails at key locations, assessing potential improvements to travel lanes and shoulders, constructing drainage ditches, curb and gutter along the roadway, replacing drain pipes and installing catch basins to adequately move stormwater.
Geotechnical field exploration helps us identify site conditions that we need to consider when planning this project.
