Yes, road construction can add to congestion in the northern areas, particularly during peak travel months. Temporary lane closures and controlled traffic flow often slow movement.
Why Construction Causes Delays
Mountain highways and valley roads are frequently upgraded or repaired due to weather damage and increasing traffic demand. Construction zones may reduce two-way roads to single-lane movement, requiring vehicles to wait for alternating clearance.
During summer, when traffic volume is already high, even short construction stretches can create noticeable delays. Heavy machinery and uneven road surfaces may also slow average driving speed.
When Congestion Increases
- Construction overlaps with weekend travel
- Repair work follows landslides or storm damage
- Narrow mountain sections limit overtaking
Checking route updates before departure and allowing extra travel time helps manage delays. While improvements enhance long-term road quality, short-term congestion is common in active work zones.
