Route 1 Over Hagatna River Bridge NOW Reduced From 3 to 2 Lanes in Each Direction


Guam – Route 1 Marine Corps Drive between Route 4 and Route 8 over the Hagatna River Bridge has now been reduced to 2 lanes in each direction Hagåtña between Route 8 and Route 4.
In preparation for the bridge replacement, the inner north and inner southbound lanes have been closed off so that crews can begin the demolition of the median and lay temporary asphalt and pavement markings. 

DPW says that 2 lanes will be open in each direction at all times and access to businesses in the area will be maintained.

Signage as well as safety and traffic personnel have been put in place to ensure the safety of construction crews and travelers through the construction area. Motorists are advised to expect some delays during peak travel hours in the mornings and evenings. The DPW asks all drivers to carefully heed all traffic signs in the area and to seek alternative routes and/or adjust drive times when feasible.


What is the scope of the project?
This project provides for improvements to the Route 1 and Route 8 intersection, and replacement of the Route 1 and Chalan Santo Papa bridges over the Agana River. The project includes pavement widening and strengthening, new curbs and gutters, improved drainage, driveways, signage, pavement markings, intersection lighting and utility relocations, as well as traffic signal system improvements.

Traffic Impacts?
During construction of the bridge on Route 1, the contractor will be closing one lane in each direction during daytime hours, leaving two lanes in each direction open to traffic.

During night hours, the contractor may restrict the open lanes to one lane in each direction and all lanes may be closed and traffic detoured up to 15 nights during the 24 month project if required. During construction of the bridge on Chalan Santo Papa Juan Pablo Dos, the street will be closed to thru traffic; however this will not occur until after the completion of the work on the intersections at Route 1 and Route 8 and substantial completion and opening of three lanes in each direction across the new Route 1 Bridge.

The contract requires that access to businesses must be kept open during construction; however some disruption to business as usual should be anticipated during the course of the project.

Where is the project located?
The project begins at the intersection of Routes 1and 8 through to Route 4. It also includes Chalan Santo Papa Juan Pablo Dos road in the village of Hagåtña.

How much is this project going to cost?
This project is approximately $16.4 million funded by the Federal Highway Administration and the Department of Defense.
