Project Overview
To address existing noise concerns on State Route (SR) 85, VTA is working with cities along SR 85 and Caltrans to study, test, and implement noise reduction treatments through a three-phase process:
- Phase 1 (Completed): This phase utilized available noise studies to evaluate alternative noise reduction measures that could be implemented with Caltrans approval, identified test locations, selected five (5) representative test locations, and analyzed feasible noise reduction at each test location. View Phase 1 Final Report here.
- Phase 2 (Current): This phase involves the pilot testing of the recommended noise reduction measures identified in Phase 1 at the five (5) test locations and evaluation of their efficacy after implementation.
- Phase 3: This phase involves implementing the measures from Phase 2 that show promise in reducing noise at other sensitive receptors along SR 85.

Objectives
The SR 85 Noise Reduction Project Phase 2 will construct noise reduction measures that include pavement overlays or other pavement surface treatments at select locations along SR 85. The purpose of the project is to test the effectiveness of noise reduction measures at the five locations identified in the SR 85 Noise Reduction Study (Phase 1) completed in September 2016. The results of these tests will be used to evaluate the costs and benefits of possible corridor-wide measures (Phase 3) at some point in the future.
Pilot Testing Locations
The specific recommended noise reduction measures at each location may change based on additional input from Caltrans and other stakeholders. The five test locations along SR 85 are listed below:
| Location A | SR 85 west of Cahalan Avenue Undercrossing in San Jose. 1,200 feet of pavement surfacing to reduce noise generation for the vehicle tire/pavement interface. |
|---|
| Location B | SR 85 near the Cox Avenue Overcrossing in Saratoga. 3,500 feet of pavement surfacing to reduce noise generation for the vehicle tire/pavement interface. |
|---|
| Location C | SR 85 between McClellan Road Overcrossing and S. Stelling Road Overcrossing in Cupertino. 2,600 feet of pavement surfacing to reduce noise generation for the vehicle tire/pavement interface. |
|---|
| Location D | SR 85 near S. Bernardo Avenue/The Dalles intersection in Sunnyvale. 2,800 feet of pavement surfacing to reduce noise generation for the vehicle tire/pavement interface. |
|---|
| Location E | SR 85 near Lubich Drive in Mountain View. 1,600 feet of pavement surfacing (both northbound and southbound) to reduce noise generation for the vehicle tire/pavement interface. |
