Below is the work notice from the Gold Line Foothill Extension Construction Authority, the agency building the 11.5-mile project that will extend the Gold Line from eastern Pasadena to the Azusa/Glendora border. The project, funded by Measure R, is currently scheduled to open in early 2016. The work notice:

WHO:  Residents / Commuters / Businesses in the Cities of Monrovia and Duarte.

WHAT: Construction of the new light rail street-level grade crossing at Mountain Ave just north of Duarte Rd will be completed this week, two months ahead of schedule. Crews will be transitioning work on Mountain Ave to the second phase, which will require a full closure of the southern half of Duarte Rd on Mountain Ave for approximately three months. The second phase of work is needed to realign the intersection to improve visibility for the traveling public and future trains, as well as install new storm drains, traffic signals, sidewalks and crosswalks.

To prepare the two streets for the second phase of work, a full weekend closure of the Mountain Ave/Duarte Rd Intersection will take place this coming weekend – Friday, August 22 at 9 p.m. through Sunday, August 24 at 9 p.m. (24-hours a day). The intersection of Mountain Ave and Duarte Rd will be fully closed to traffic in all directions during this weekend’s closure.

Friday, August 22, 2014 at 9:00 p.m. thru Sunday, August 24, 2014 at 9:00 p.m.: The intersection of Mountain Ave and Duarte Rd will be closed to thru-traffic to reconfigure the traffic lanes and prepare for the second phase of work at the intersection. On August 24 at 9:00 p.m., the northern portion of the Mountain Ave/Duarte Rd intersection will fully re-open, as will one lane of traffic in each direction on Duarte Rd. The southern portion of the intersection will be closed, for approximately three months.

About the Foothill Gold Line Construction Authority: The Construction Authority is an independent transportation planning and construction agency created in 1998 by the California State Legislature. Its purpose is to extend the Metro Gold Line light rail line from Union Station to Montclair, along the foothills of the San Gabriel Valley. The Construction Authority built the initial segment between Union Station and Pasadena and is underway on the Foothill Gold Line. The Foothill Gold Line is a nearly $2 billion extension that will connect Pasadena to Montclair in two construction segments – Pasadena to Azusa and Azusa to Montclair. The 11.5-mile Pasadena to Azusa segment is on time and on budget, and will be completed in late-September 2015 when it will be turned over to Metro for testing and pre-revenue service. It is fully funded by LA County’s Measure R. Metro will determine when the line will open for passenger service. Three design-build contracts, totaling more than $550 million, are being overseen by the Construction Authority to complete the Pasadena to Azusa segment. The Azusa to Montclair segment is environmentally cleared and is undergoing advanced engineering and design. It will be shovel-ready for a design-build contract in 2017. The $1 billion segment is currently unfunded for construction.
