A rockslide shut down a mountain highway in eastern Taiwan early Tuesday morning, but crews cleared it within four hours — bad news for morning travelers, quickly resolved.

• Rocks came down on Highway 20 near Lidao in Haiduan Township, Taitung, at 6am, blocking traffic in both directions.
• Days of heavy rain from a low-pressure band and strong southwest winds loosened the slope.
• Road crews sent contractors and heavy machinery in; one lane reopened by 9am and full traffic by 10am.
• The road is a key east-west link across southern Taiwan's mountains, so closures cut off remote communities fast.

Outlook: More rain in the forecast keeps the risk of further slides on this stretch high.
