A traffic collision on State Route 4 (SR-4) in Discovery Bay, CA, caused significant disruptions to traffic today. The incident occurred around 3:35 PM and involved two vehicles: a black four-door sedan that spun out due to a blown tire and a white sedan. The black sedan was blocking the westbound lane, leading to lane closures and traffic delays during the busy afternoon commute.

Emergency response units quickly arrived at the scene to manage the situation and restore normal traffic flow. A tow truck was called to remove the black sedan, which was unable to be driven due to the damage. The white sedan remained drivable but was also involved in the collision.

As a result of the lane blockages, motorists experienced delays and congestion in the area. Traffic was significantly impacted until approximately 4:16 PM when all lanes were cleared, allowing for the resumption of normal traffic conditions.

Drivers in the vicinity of Discovery Bay are advised to remain cautious and aware of potential residual delays as traffic resumes. This incident underscores the importance of vehicle maintenance, particularly tire conditions, to prevent similar traffic incidents in the future.
