Caltrans District 5 is preparing to install centerline rumble strips and edge line rumble strips on several state highways in San Luis Obispo and Santa Barbara Counties, including Route 166, Route 33, Route 154, and Route 246. The project targets high-risk locations identified through the Cross Over Collisions Monitoring Program, aiming to reduce the frequency and severity of crossover and run-off-the-road crashes by providing audible and tactile warnings to drifting vehicles. Rumble strips are recognized as an effective, low-cost safety improvement to enhance driver awareness and alertness, particularly on stretches of road with a history of such incidents. The primary beneficiaries are the traveling public using these corridors, with the installation expected to improve overall roadway safety without significant disruption. The project is forecasted for release in July 2026, with Shelby Fredrick serving as the Environmental Coordinator for inquiries and project coordination.

All unit prices are defined as all-inclusive, covering design, engineering, project management, quality control, equipment, transportation, installation, utilities, insurance, bonds, and warranty. The contract requires submission of both a technical proposal capped at 40 pages and a separate price proposal via the Bid Express platform, with a mandatory 5% bid bond. The technical evaluation is weighted 65% toward the design-build technical approach and 35% toward project management and coordination, with strict pass/fail gates for submission compliance, proper organization, and bid bond submission. The project must be completed within 2,039 calendar days from the anticipated Notice to Proceed date of December 8, 2026, with adjustments allowed if the completion date falls between December 1 and March 15. MassDOT mandates strict adherence to state laws, including MGL Chapter 149A (public construction labor standards), Chapter 268A (conflict of interest), and Chapter 30, §39M1/2 and §151/2 (procurement compliance). The contractor must implement a comprehensive Quality Control System with dedicated full-time managers for design, construction, and fabrication oversight, including independent oversight at fabrication plants beyond the fabricator’s own program. Non-conformance reports must be mitigated through defined procedures. Affirmative Action and Equal Employment Opportunity compliance is required, with firms of 50 or more employees and contracts over $50,000 needing an approved affirmative action plan on file with MassDOT.

The contractor is responsible for all bonding, including performance and payment bonds for the full contract amount, and must comply with insurance and risk management standards.
