Road Construction

Traffic signal safety upgrades

The City of San Marcos is updating traffic signals citywide with new retroreflective backplates — bright yellow borders around signal lights — to improve visibility and safety for drivers, especially at night and during power outages. 

Minor traffic impacts are expected at each location while work is completed.

Major city construction projects affecting traffic will be posted to this page. 

The city appreciates the community’s patience as we continue making roadway safety improvements across San Marcos.
