The quickest and easiest way to reach our facility from most of the San Francisco Bay Area is on State Highway 4.

• As you drive eastbound on Highway 4, you should pass the first Lone Tree Way exit you encounter in Antioch and instead continue on Highway 4 toward Stockton.
• Take the "Lone Tree Way" exit and turn right at the bottom of the ramp onto Lone Tree Way.
• Diablo Analytical is located on the right, three blocks down Lone Tree Way in the back row of buildings of the Venture Commerce Center.

Note 1: The new section of Highway 4 may not yet be programmed into many GPS map databases.

Note 2: Highway 4 is a significant commute route. Consequently, you should try to plan your visit to avoid westbound traffic during the morning commute (approximately 6-9 AM) and eastbound traffic during the afternoon commute (approximately 3-7 PM).
