I-17 bridges in Munds Park ready for upgrades

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.
