Highways, Rail, and Express Routes: Navigating the Cross-Island Corridor
Driving between Alghero and Olbia offers the most flexible and direct route across northern Sardinia. Motorists primarily utilize the modernized SS729 Sassari-Olbia highway, connected via the SS291var from Alghero. This four-lane thoroughfare has significantly reduced historical travel bottlenecks, allowing drivers to bypass winding rural roads and complete the 135-kilometer journey in under two hours under normal traffic conditions.
Public transit users rely heavily on regional rail networks operated by Trenitalia and regional bus routes managed by ARST and private carriers. While there is no direct non-stop rail link connecting Alghero's station directly to Olbia, smooth transfers at Sassari or Ozieri-Chilivani allow passengers to traverse the island affordably. Seasonal direct coach services operate during peak months, offering non-stop connections between Alghero Airport (AHO) and Olbia Costa Smeralda Airport (OLB).
Summer Peak Logistics: Managing High Traffic Volume and Ticket Availability
Mid-August represents the absolute peak for travel demand across Sardinia. Increased visitor volume significantly impacts major transit nodes, particularly car rental desks at both Alghero and Olbia airports. Vehicle availability often reaches capacity, prompting travel authorities to urge visitors to secure rental reservations well in advance.
Key considerations for peak-season travel include:
- Departure Timing: Departing before 8:00 AM or after 7:00 PM helps drivers avoid heavy congestion along the SS729 near the Olbia city entrance and coastal access points.
- Train Transfers: Passengers using Trenitalia services should double-check connection windows at Chilivani, allowing at least 15 minutes for transfers between regional trains.
- Bus Ticket Pre-booking: Express seasonal buses require advance digital booking during August to guarantee seating, as walk-up tickets often sell out quickly.
- Airport Connections: Travelers connecting between AHO and OLB flight terminals should allocate a minimum 3.5-hour buffer to account for traffic or check-in queues.

Infrastructure Modernization: 2026 Transit Outlook and Multi-Modal Plans
Regional authorities in Sardinia continue to invest in modernizing the northern transit axis. Infrastructure projects throughout 2026 have focused on finalizing residual roadwork sections along the SS729 corridor and integrating smart traffic management systems. These enhancements aim to maintain steady traffic flow and lower accident rates along key junctions near Monti and Enas.
Looking ahead through the remainder of 2026, Sardinia's regional transport plan emphasizes improved intermodality. Upgraded signaling systems on the rail line between Sassari and Olbia are scheduled to reduce train transit times by up to 15 minutes. Additionally, expanded electric vehicle charging networks along major highway service plazas are making cross-island EV travel more accessible than ever for environmentally conscious travelers.
