While Seattle’s summer weather had been relatively mild in recent weeks, hotter temperatures have arrived, with highs near the lower 90s expected much of this week. It is important we keep our streets and bridges cool as intense heat can cause damage. Thankfully, our crews are standing by and ready to respond to any weather-related damage such as sink holes or fissures.
These rising temperatures also means we are preparing to conduct bridge cooling on the University, Fremont, and Ballard bridges.
We will begin to proactively spray down our steel bridges with water when temperatures hit sustained periods 85 degrees or higher, as part of our ongoing bridge maintenance program. This cooling method also helps to reduce the likelihood of the steel to expand and potentially create problems for bridge opening and closing functions.
When we spray down the bridges, we close each bridge for a few minutes multiple times throughout the day. To ensure the water is safe for the environment, we also add a small amount of vitamin C to neutralize the chlorine in the water.
Safe travel reminders
If you plan on heading out during warmer weather, please stay safe! Biking, walking, and rolling can be fun ways to enjoy hot summer days, but can also be dangerous if you’re not careful. Always bring plenty of water and don’t push yourself past your limits. If you’re feeling light headed, take a break and move out of direct sunlight.
When you need to travel, please make sure to follow these tips to stay cool and safe.
Use sun protection: Take sunscreen, an umbrella or a wide-brimmed hat, and wear loose-fitting, light-colored cotton clothing.
Hydrate: Always carry water with you, and drink plenty throughout the day. If applicable, locate water bottle fill up stations or water fountains when outdoors, in case your water gets low.
Plan ahead: Before heading out, check the weather, traffic conditions, and travel times if you’re taking public transit to avoid standing in direct sunlight for too long. Always familiarize yourself with routes or maps before you go.
Check your vehicle: If you’re driving, checking to make sure your vehicle is in good operating condition can help you avoid breakdowns or tire blowouts. Check your air conditioner and coolant levels. Top off any vital engine fluids and make sure your battery is working. Also check your tire pressure before driving, as the combination of underinflated tires and hot pavement can lead to a blowout.
Fuel up: Keep your tank at least three-quarters full. Running out of gas, especially in a remote location, is dangerous in intense heat.
Get help: If your vehicle breaks down in extreme heat, call for assistance right away and run the air conditioner. If the A/C isn’t working, roll down all windows.
Wait safely: If the temperature inside your vehicle becomes too hot, everyone, including pets, should exit carefully. Seek out or create a shaded area as far away from the travel lanes as possible. Be careful walking on the street surface, which can be hot enough to burn skin. Keep your shoes on and try to keep your pets’ paws off the pavement. If you’re stopped along the highway, raise the front hood and turn on hazard lights. Please keep in mind that parking in tall brush can start a fire.
Avoid risky behaviors: You know the rules: Don’t text or drive distracted, obey posted speed limits, and always drive sober. Both alcohol and drugs can cause impairment. It’s illegal to drive impaired by any substance in all states – no exceptions. Alcohol and drugs can impair the skills critical for safe and responsible driving. This includes coordination, judgment, perception, and reaction time.
