- Please follow all public smoking, vaping, littering, and loitering laws while on tunnel property.
- Pets are allowed but they must be on a short leash.
- Groundwater will always be dripping down the walls and from above in some places. Consider wearing a hat, jacket, or rain poncho.
- The walking surface will be wet & slippery in some sections. Please wear proper footwear for traction.
- Please be safe and proceed at your own risk.
- Thank You!
