Pavement Improvements

Las Tunas Drive Pavement Rehabilitation Project

Las Tunas Drive San Gabriel


Designed as the widest section of roadway in the city of San Gabriel in the early 1900s, this section of Las Tunas Drive was once zoned for two Pacific Electric Railway tracks and four lanes of traffic.  

This is the city’s largest paving project in nearly a decade. The $3 million pavement rehabilitation project will reconstruct Las Tunas Drive, which is a nine lane road, from Muscatel Avenue to San Gabriel Boulevard (about one mile). The project will also involve pavement recycling, a cost-effective, time-reducing and  environmentally friendly technology we’re using for the first time in San Gabriel.


  • Extensive road repairs along Las Tunas Drive from San Gabriel Boulevard east to Muscatel Avenue.
  • Construction to include curb extensions at several corners to reduce crossing distances for pedestrians and to allow for installation of curb ramps that meet the standards of the federal Americans with Disabilities Act.
  • The city's first bike lanes.
  • Spot sewer repairs.


Construction underway, to be completed summer 2015.

Below are answers to some of the frequently asked questions about the Las Tunas Drive Pavement Rehabilitation Project.

Q: Why is the city paving this particular section of road?
This portion of Las Tunas was the major arterial that was the most traveled and in the worst shape. The roadway had become more expensive to maintain than the cost of repaving the whole street.

Q: There are other streets in need of repair, when will the city pave Del Mar Avenue?
As far as other road projects in the future, the city is in the final stages of obtaining a $3.8 million loan through the California Infrastructure Bank that would fund reconstruction of Del Mar Avenue from Mission Road to the I-10 freeway. If approved by the state and by the San Gabriel City Council, the work would be completed in 2-3 phases over a period of two years or so. The first phase could begin early next year. A portion of the project area needs sewer rehabilitation and that work will need to take place before pavement repairs can begin. If everything goes smoothly, the paving could be complete by the end of 2017.

Q: Construction messes with my commute and drop off, why is the city doing this during the school year?
This is major reconstruction of a busy arterial and there is certainly some degree of inconvenience involved. The contractor is working quickly and City inspectors and project managers are monitoring the project to make sure that traffic delays are kept to a minimum. It would not be possible to finish the project within the duration of the school summer vacation. The good news is that the project will be complete in time for the start of the 2015-16 school year.

Q: Why is the city building curb extensions (bulb-outs) on the corners of the street?
: Las Tunas Drive is the widest street in the city and this section has more lanes than necessary to carry the traffic on Las Tunas Drive. Curb extensions visually and physically narrow the roadway, creating safer and shorter crossings for pedestrians. The extensions also allow the city to build curb ramps for disabled accessibility and, in some cases, the city will be using the area to infiltrate storm water to improve water quality and help recharge groundwater for drinking.

Q: I keep hitting these curb extensions. Aren’t they dangerous?
: These curb extensions do not stick out into the travel lane, so no vehicle driven properly should ever hit them. They will be more visible once the new pavement is installed and they will be five feet away from the nearest vehicle travel lane once the bike lane striping is painted.

Q: Why is the city taking away parking for these curb extensions?
: The curb extensions are only built at the corners where parking was never allowed.

Q: Why isn't the city installing curb extensions on the south side near Burton?
: School traffic often backs up past this intersection along the curb parking lane.
