Have you noticed anything different on some of the new roads lately? Lane lines are gaining weight. Those longitudinal traffic lines separating lanes have historically been 4 inches wide, now they are six inches. Sarah Huffman, PE at Wallace Group explains that Caltrans has started implementing wider stripes for several reasons; such as they improve roadway guidance during poor visibility conditions and will serve the aging driving population. These changes will also benefit the emerging self-driving car market. Navigation for these new vehicles will rely on the marking on California’s 50K miles of roadways and according to Caltrans they aim to have these changes completed in two to three years.

We ❤️ @SLO parks and rec! We attended the first of their “Emerging Trends” presentations last night and heard from the community regarding the love and high priority needs for Sinsheimer Pool. We also enjoyed a preview of awesome events that Dave has planned to activate our parks. Don’t miss the next presentation, February 6, 5pm at the Council Chambers. Especially if you have an interest in furry friends, two-wheeled transport or plants 🌱

On Tuesday morning, a group of team members from Wallace Group, RRM, the County of SLO, and Caltrans met at the Ontario Ridge trailhead of Bob Jones Trail and set out to map the course for the new segment of the trail. The proposed trail will provide more than 4 miles of new pathway for bikes and pedestrians between Avila Beach and southern San Luis Obispo. Throughout the day the group traversed overgrown creek beds and wooded terrain, as well as open grasslands and charming apple orchards while collaborating on ideal trail alignments, creek crossings, and vista points. It was a beautiful day, and someday we will all be able to enjoy this new scenic trail between the city and the sea!
