The return journey for millions of travelers following the Qingming Festival has hit a critical bottleneck on the east coast, with the 清明節北返車潮 (Qingming Festival northbound traffic surge) triggering severe delays. The most acute congestion is currently centered on National Highway 5, where the stretch between Yilan and Toucheng has reached a “purple alert” status, signaling extreme gridlock that is expected to persist well into the early hours of tomorrow morning.
For many drivers, the journey home has shifted from a commute to a standstill. Real-time traffic monitoring indicates that speeds in the most affected zones have plummeted to as low as 14 kilometers per hour, effectively turning a high-speed artery into a parking lot. The surge is a result of synchronized departures from holiday destinations, overwhelming the capacity of the limited routes connecting Yilan and Hualien to the northern metropolitan areas.
Transportation officials are warning that the volume of vehicles is not expected to subside quickly. Even as some segments of the highway system are moving, the concentrated pressure on the Yilan-Toucheng corridor has created a ripple effect, causing secondary congestion across multiple connecting road networks.
The ‘Purple Alert’ and the Yilan-Toucheng Bottleneck
The “purple alert” designation is reserved for the most severe levels of traffic saturation. On National Highway 5, the northbound lane from Yilan toward Toucheng has become the primary point of failure. This specific segment serves as the sole gateway for traffic leaving the Yilan plains toward Taipei, making it highly susceptible to volume spikes during major holidays.

Current data highlights 14 specific high-risk congestion points across the network. The intensity of the gridlock is not merely a matter of slow movement but of complete saturation, where the density of vehicles prevents the normal flow of traffic even during gaps in volume. Authorities estimate that the current level of saturation will keep these roads congested until the early hours of the following day.
The impact is felt most heavily by those traveling from the east coast, as the National Highway 5 bottleneck acts as a final filter before drivers can merge onto National Highway 1 or 3. This has led to an accumulation of vehicles at various interchanges, extending the delays far beyond the primary purple-zone segment.
Regional Pressure: Suhua Highway and East Coast Flow
The congestion is not limited to the expressways. The Ministry of Transportation and Communications has noted significant pressure on the Suhua Highway, the vital link between Hualien and Yilan. Traffic flow on the Suhua northbound route saw a dramatic surge between 10:00 a.m. And 11:00 a.m., as travelers began their trek north in waves.
This timing created a “domino effect”: as the bulk of the Suhua Highway traffic arrived in Yilan, it collided with local holiday travelers, funneling an unsustainable number of vehicles onto National Highway 5 simultaneously. This convergence is the primary driver behind the current “purple” status of the Yilan-Toucheng stretch.
Travelers are currently facing a fragmented experience where some sections of the journey are fluid, while others are virtually impassable. This unpredictability has led many to seek alternative routes, though most secondary roads in the region are also seeing increased volume, offering little relief to those attempting to bypass the main arteries.
Estimated Traffic Impact Summary
| Route Segment | Status/Alert Level | Peak Impact Window | Expected Duration |
|---|---|---|---|
| National Highway 5 (Yilan-Toucheng) | Purple (Severe) | Afternoon/Evening | Until early tomorrow |
| Suhua Highway (Northbound) | High Volume | 10:00 a.m. – 11:00 a.m. | Intermittent |
| National Highway 1 & 3 (Various) | Moderate to High | Evening Peak | Late Night |
Navigating the Gridlock: Advice for Travelers
With 13 different sections of the national highway system expected to experience delays, the current recommendation for those still on the road is patience and strategic timing. The Freeway Bureau suggests monitoring real-time updates via official apps and signage to identify the least congested windows for movement.
Drivers are urged to avoid sudden lane changes in the saturated Yilan-Toucheng segment, as these maneuvers often trigger “phantom” traffic jams, further reducing the already low average speed of 14 km/h. For those who have not yet departed, delaying the trip until after midnight may significantly reduce the time spent in stationary traffic.
Stakeholders, including local police and highway patrol, have increased their presence at key interchanges to manage merging traffic and respond quickly to any accidents that could further paralyze the corridors. Given the density of the 清明節北返車潮, even a minor fender-bender can result in hours of additional delay for thousands of vehicles.
For those seeking the most accurate, up-to-the-minute data, the Freeway Bureau’s real-time traffic map remains the authoritative source for monitoring the transition from purple to yellow or green alerts.
Traffic monitors will continue to track the dissipation of the Yilan-Toucheng bottleneck throughout the night. The next critical checkpoint will be the early morning commute tomorrow, where officials will assess whether the holiday backlog has cleared sufficiently to allow for normal weekday traffic volumes.
