Caltrans to implement SR 78 afternoon metering

In response to changing demographics and evolving travel patterns, the Department of Transportation (Caltrans) will begin afternoon ramp metering for the westbound entrance ramps on SR 78 from Nordahl Road to Sycamore Avenue between 3 and 7 pm. Motorists may experience slight delays during metering periods at effected westbound freeway on-ramps. 
The westbound metering activation schedule is as follows:

Wednesday, June 12
• Sycamore Avenue to SR 78 (Vista)
• Rancho Santa Fe Road to SR 78 (San Marcos)
• Las Posas Road to SR 78 (San Marcos)

Wednesday, June 19
• San Marcos Boulevard southbound to SR 78 (San Marcos)
• San Marco Boulevard northbound to SR 78 (San Marcos)
• Twin Oaks Valley Road southbound to SR 78 (San Marcos)
• Twin Oaks Valley Road northbound to SR 78 (San Marcos)

Wednesday, June 26

• East Barham Drive to SR 78 (San Marcos)
• Nordahl Road to SR 78 (San Marcos)

Ramp metering will decrease the length and severity of traffic congestion for westbound traffic and will improve the overall traffic flow along the SR 78 corridor, ultimately reducing door-to-door travel times.
