Guam – The Department of Public Works has issued the following advisories on road construction projects that may cause traffic headaches in the week ahead. Route 1 in Yigo
Drivers are advised that construction work for the new traffic signals and road work at Chalan Lujuna and Wusstig Road will require that Marine Corps Drive be restricted to short one lane detours during daylight hours. These lane restrictions will result in delays an increased travel time for traffic heading to and from Anderson.
Route 25 Alageta Road
Drivers using Alegeta Road when traveling from the airport are advised that construction work between Chalan Ancho Latte and Chalan Akudi will be starting. Traffic heading toward Route 16 will be detoured onto Bari Asi Street. Traffic heading from Route 16 will be detoured from Alageta Road onto Chalan Akudi Street.
Drivers continue to be advised that Alageta Road is closed to all but local traffic from Chalan Akudi to Route 26. Drivers traveling through this area are requested to slow down in the construction area and on the local streets.
Route 4 from McDonalds to Route 10
The paving work to finish up the Tutujan (Sinajana) intersection is expected to be completed within the next 2 to 3 weeks. Until then traffic lanes at the intersection will be restricted to one lane in each direction. Drivers are requested to follow the construction signs for the reduced lanes and merge early into the thru lanes.
Route 8/10/16 (Tri-Intersection)
Traffic lanes at the Tri-Intersection will continue to be restricted to one lane in each direction. The concrete work for the new roadway is proceeding and traffic lanes are anticipated to be moved to the new pavement in late January. Drivers on Route 8 are requested not to block the emergency access in front of the Barrigada Fire Station when waiting for the traffic signal to change.
Route 4 (Yona)
Drivers heading to and from Yona are advised that lanes have been shifted for the construction work near the outlook. Drivers are advised to follow the construction signs that shift the lanes of traffic and reduce their speeds in the construction area.
Route 2 (Umatac)
Drivers using Route 2 in Agat and Umatac are advised that traffic lanes have been shifted at Cetti River. Drivers are requested to look well in advance for the construction signs that shift the lanes of traffic and to reduce their speed in the construction area.

This road project consists of widening and strengthening the pavement along with drainage improvements. Construction work began last week and is expected to be completed in June of 2011. Until the work is completed drivers should anticipate lane restriction, increased travel time and short delays.

Traffic Question & Answer Building a road is so much more than laying pavement. In this week’s traffic update, we will begin a Question and Answer series on traffic and roadway questions. If you have any questions you would like to see featured in our weekly traffic update, please send them to firstname.lastname@example.org or call us at 646-3452.
Q: Why are there two layers of pavement on Guam’s roads?
A: Road construction on Guam requires two different types of asphalt pavement to be used.
The bottom layer is made of limestone aggregates (rocks) from here on the island. Over time these aggregates have a tendency to become very smooth from the friction of the car tires that pass over the roadway. This makes the road slick, especially when it is raining.
To make the road less slick the top layer of pavement uses a different kind of aggregate (rocks). These aggregates are imported from off island and are very resistant to becoming slick from the friction of the car tires.
