Itzulia Cycling Race: Traffic Disruptions Expected in Basauri, Ugao, and Balmaseda

The Basque Country is preparing for the arrival of the Itzulia, with significant traffic modifications scheduled across Bizkaia. For residents and travelers in the region, the day’s commute will be heavily influenced by the race route, which centers on the industrial hub of Basauri.

According to event details, the race is set to both start and finish in Basauri, following a course that includes a brief passage through the province of Álava. These logistics mean that the Greater Bilbao area, particularly the corridors connecting the river valleys, will experience the most substantial impact on vehicle movement.

Traffic Impact Zones in Bizkaia

Authorities have highlighted several key areas where traffic cuts are planned to ensure the safety of the riders and spectators. The primary zones of disruption include:

• Basauri: As the designated start and finish line, this municipality will notice the most intensive closures.
• Ugao: Expected traffic modifications as the race progresses through the region.
• Balmaseda: Planned cuts to accommodate the cycling peloton.

Because the race utilizes the unique geography of the region, motorists are advised to seek alternative routes, especially when navigating the lower valley of the Nervión and Ibaizabal rivers.

Spotlight on Basauri: The Race Hub

Basauri serves as a critical logistical point for the Itzulia. Located in the historical territory of Biscay (Bizkaia), the town is a major municipality within the Greater Bilbao conurbation. Its position at the confluence of the Nervión and Ibaizabal rivers—the two longest rivers in Biscay—makes it a natural crossroads for the region.

For those unfamiliar with the area, Basauri is a predominantly industrial town that grew significantly after separating from Arrigorriaga in 1510. The town’s layout is defined by the river plain and a series of meanders, which are now largely occupied by industrial facilities. The neighborhood of Bidebieta, which translates to “two roads” in Basque, underscores the town’s role as a meeting point for roads arriving from Durango and Orduña-Urduña.

This geographical convergence is precisely why the town is an ideal starting and ending point for a major cycling event, though it likewise explains why traffic diversions in this specific area can create ripple effects throughout the metropolitan region of Greater Bilbao.

Note for travelers: Basauri’s high population density—approximately 5,750 people per square kilometer—means that road closures are likely to cause significant congestion on secondary roads.

Route Overview and Regional Context

The Itzulia’s itinerary emphasizes the diverse landscape of the Basque Country. While the core of the day’s activity remains in Bizkaia, the race will venture briefly into Álava before returning to the finish line in Basauri.

The transition between these provinces often involves navigating challenging terrain and narrow roads, further necessitating the strict traffic controls in place today. The utilize of the Basauri municipality as the anchor for the event places the race in the heart of a region known for its industrial heritage and strategic river valleys.

What to Expect Today

With the race starting and ending in the same location, the traffic pressure on Basauri will be bifurcated—initial closures for the start and a second wave of restrictions as the riders return for the final sprint.

Drivers are encouraged to stay clear of the river plains and the primary arteries connecting the Greater Bilbao area to the interior of Bizkaia. Local authorities typically implement rolling closures, but the start and finish zones in Basauri will likely remain restricted for longer durations.

The next confirmed checkpoint for the event is the arrival of the peloton back in Basauri for the final stage of the day’s competition.
