Road improvements slated for San Marcos
San Marcos, CA – The City of San Marcos will begin roadway structural repairs to San
Marcos Boulevard, Grand Avenue and Rancho Santa Fe Road on January 22, 2008. The structural repairs involve the removal and replacement of distressed asphalt concrete within approximately eight miles of roadway pavement. The work is being performed in order to enhance the structural integrity of the roadway and to make it safer and easier for motorists to travel on San Marcos arterial roadways.
Exact roadway segments include:

  • San Marcos Boulevard from Grand Avenue to Rancho Santa Fe Road
  • San Marcos Boulevard from Twin Oaks Valley Road to Knoll Road
  • Grand Avenue from Rancho Santa Fe Road to San Marcos Boulevard
  • Rancho Santa Fe Road between Melrose Drive and Meadowlark Ranch Road

Work will begin on Tuesday, Jan. 22 and will take approximately 25 working days to
complete. Construction crews will perform a majority of the work in the late evening hours
as a courtesy to motorists. However, as a courtesy to surrounding residents who would be
affected by construction noise, work on the section of San Marcos Boulevard between
Twin Oaks Valley Road and Knoll Road will be performed during the daytime.
The City is investing $695,058 for this road improvement project.
“These roadway structural repairs are needed to make traveling on these heavily used
streets more efficient and safe for our motorists,” explained Director of Public Works Mike
Mercereau. Motorists are advised to use caution when traveling in construction zones. Some minor delays may be experienced.
