Memorial Day weekend is here and if you’re headed out of town you probably have your travel plans all wrapped up by now.

Hopefully those plans already include some safety preparations … if not, here are a few things to think about before hitting the road!

• Check out your vehicle’s condition before a trip. Inspect things like tire condition and pressure, oil and other fluid levels and inspect belts and hoses.
• Pay attention while out on the road and expect the unexpected.
• Get plenty of rest before traveling and take regular rest breaks.
• Be patient and alert to changing road conditions … and buckle up!
• If your vehicle breaks down or you need to change a flat tire, pull completely off the roadway. Be cautious in areas with taller grass or brush – hot vehicle components can spark a fire.
• Don’t drive under the influence of alcohol or drugs (even prescription drugs can limit your ability to safely operate a motor vehicle).
• Cell phones or satellite devices help in an emergency – make sure they are fully charged.
• Obey the posted speed limit and check for changing speed limit conditions.
• Signal in advance for lane changes and turning maneuvers.
• Take plenty of food and water.
• Slow down in areas known for high winds and dust storms and be prepared to exit the roadway if extreme weather conditions occur. Weather conditions can change and monsoon storms can arrive suddenly, creating dust-filled winds and cutting visibility along the highway up ahead.

It’s always a good idea to allow some extra travel time, too. Unscheduled closures due to crashes or other incidents, including wildfires, can affect highway travel. Existing work zones for highway improvement projects, even when work is not taking place over holiday weekends, can add time spent on the road.

A couple of existing highway work zones to be aware of – especially at the start and end of the Memorial Day weekend – are located along Interstate 10 at the Hassayampa River bridges 40 miles west of downtown Phoenix and at the Interstate 17 bridges at Munds Park 20 miles south of Flagstaff. The highways are narrowed to one lane in each direction at those locations.

One last thing … before your trip you can call 5-1-1 or log on to ADOT’s Traveler Information site at az511.gov to check on updated highway conditions around the state.

The bridges over Pinewood Boulevard in Munds Park have been carrying Interstate-17 traffic for the past 53 years and now it’s time for some well-deserved reconstruction!

ADOT has already begun the project that will rebuild the bridges and ramps on I-17 at Munds Park, an area just south of Flagstaff . Work started last month and is scheduled to wrap up by fall 2012.

When the job is finished, motorists will have two new bridges each measuring 100-feet long (they’re now just 25 feet). The bridges will also be wider to accommodate an eventual third lane planned for I-17. A new sidewalk on Pinewood Boulevard is going in, too. It will allow pedestrians to cross safely underneath I-17 (see above video).

This update is necessary because there is more traffic now then when the bridges were built in 1958. Back then there was no development in Munds Park . The bridges are just inadequate for today’s traffic.

Drivers should expect some slowing of traffic due to this project – especially over busy holiday weekends. It is expected that delays at peak holiday travel times could reach up to 45 minutes … so please plan accordingly.

Project Timeline

April 2011 - Oct. 2011: The northbound bridge will be demolished, then reconstructed and I-17 will be repaved through the work zone. Because the northbound bridge is closed, motorists traveling northbound on I-17 will be directed to a detour that crosses over the median and utilizes southbound lanes. All on and off ramps will remain open.

April 2012 - Oct. 2012: The southbound bridge will be demolished, then reconstructed and I-17 will be repaved through the work zone. While this work is being done, the southbound bridge will be closed and motorists will be detoured over to the northbound lanes of I-17.
