Safety Tips for Pedestrians and Bikers

Moving Through an Active Construction Site:

  • Wear Reflective Clothing: Enhance your visibility to construction workers and machinery operators by wearing bright, reflective clothing. Avoid dark or earth tone colors that blend into the environment and are hard to see.
  • Use a Helmet: If you are biking through the construction zone, always wear a helmet.
  • Carry Safety Gear: Equip yourself with necessary safety gear, such as gloves and eye protection, to shield against dust and debris.
  • Keep Earbuds Out: Avoid wearing earbuds or headphones. Keeping your ears free allows you to stay alert to warning sounds and construction activity around you.
  • Follow Posted Signs: Pay attention to and obey all posted signs and instructions. These are designed to guide you safely through the construction area.
  • Watch for Uneven Surfaces: Be cautious of uneven surfaces, holes, or loose gravel. These hazards can be particularly dangerous for cyclists or pedestrians.
  • Avoid Distractions: Stay focused on your surroundings and avoid using mobile devices while navigating through the construction zone.
  • Use Designated Paths: Stick to designated pathways or detours set up for trail users. Venturing into unauthorized areas can be hazardous.
  • Communicate with Workers: If unsure, ask construction workers for directions or clarification for how to move through the area safely.

Future temporary closures/detours of Ellston Street / Sinton Trail 

  • As part of the auxiliary lane project, the aging bridges on I-25 over Ellston Street will be reconstructed and widened.
  • This work will also require several short-term, temporary closures of portions of the Sinton Trail and Ellston Street under I-25.
