How to Navigate the Tianshan Shengli Tunnel: Long-Distance Driving and Rest Stops

The Tianshan Shengli Tunnel spans approximately 22 kilometers through the main range of the Tianshan Mountains and is the most critical section on the Uwe Highway. Prolonged driving in enclosed spaces can lead to visual fatigue and reduced attention. Familiarizing yourself with the rules beforehand will help you avoid unnecessary detours.

Before entering the tunnel

Slow down to the speed limit in advance, turn on your low-beam headlights, and remove your sunglasses. Check your fuel and battery levels; there are no gas stations inside the tunnel. Set up navigation beforehand, as signal strength is weak inside tunnels and changing routes temporarily can be difficult.

Maintain a greater following distance than on normal roads; brake lights in tunnels can be difficult to judge accurately. Do not follow closely when there is heavy truck traffic.

Tunnel Rules

Do not change lanes, overtake, make U-turns, or stop. Obey posted speed limits, which are typically lower than outside the tunnel. The tunnel is monitored and equipped with emergency phones. In case of a breakdown, pull over to the side, turn on hazard lights, place a warning triangle, move to a safe area, and call for help.

Do not use high beams; they can blind drivers ahead. Air quality in tunnels is often poor, so switch your air conditioning to recirculate mode.

Fatigue and Rest

Long tunnels can cause drowsiness. If you're already tired, rest at a service area before entering. After exiting, do not accelerate immediately; allow your eyes time to adjust to the light.

Take a break after every two hours of driving. On Xinjiang routes, long stretches between services make fatigue the primary risk. See service area distribution below.Self-driving guide for Wuwei-Weiqu Expressway。

Winter Precautions

Significant temperature difference at tunnel entrances/exits; black ice may be present. Reduce speed in advance and avoid sudden braking when entering or exiting. During snowfall, tunnels may be temporarily closed; follow on-site traffic control instructions.

Why take this tunnel?

It compresses the time to cross the Tianshan Mountains into about 20 minutes, bypassing the winding and icy sections of the old route. This makes same-day round trips between Urumqi and Korla possible, saving a full half day for southern Xinjiang itineraries.

Tunnel Groups and Signals

The Wuwei-Weiqu Expressway isn't just one long tunnel—it's a series of bridges and tunnels connected in sequence. You'll enter and exit frequently, requiring your eyes to constantly adjust to changing light conditions. Maintain a steady speed; do not accelerate simply because visibility improves after exiting a tunnel.

Weak signal in tunnels may cause navigation to freeze. Check exit numbers beforehand and confirm your route after exiting. Arrange to meet at a service area with fellow travelers instead of relying on phone calls.

If a breakdown occurs in the tunnel: pull over, turn on hazard lights, place a warning triangle, move to a safe area, and use the emergency phone for help. Do not stand in the lane waving to stop vehicles.

Mountain road section after exiting the tunnel

Exiting a tunnel does not mean the entire route is at highway speeds. Some sections still have curves and grades with changing speed limits—follow posted signs. Mountain weather differs from outside; reduce speed if snow occurs.

Use a low gear to control speed on long downhill stretches; avoid prolonged braking. Overheated brakes can fail—check wheel hub temperature during rest stops at service areas.

Distance between tunnels is short. Maintain a steady speed instead of accelerating—it's safer and more fuel-efficient.

Long tunnels test your patience. With monotonous lighting and repetitive scenery, it's easy to lose focus. Maintain a steady speed, increase following distance, play music to stay alert, and avoid frequent lane changes. After exiting the tunnel, don't accelerate immediately—let your eyes adjust first. Safe passage is more important than arriving ten minutes early.

Keep a safe distance from large trucks in tunnels; their dust can reduce visibility. Switch your air conditioning to recirculate mode to minimize exhaust fumes. If you feel drowsy, stop at the nearest service area after exiting the tunnel to splash water on your face before continuing. Fatigue builds up over long drives—don't wait until you're exhausted to rest.
