After Mile 8 Intersection, the FT68 becomes a single-carriageway road but retains the 60 km/h speed limit due to its narrower condition.

After Kampung Sungai Rumput, the Jalan Gombak FT68 becomes more winding, causing the speed limit to be reduced to 50 km/h.

[2][3] From Genting Sempah, Jalan Gombak FT68 descends the Titiwangsa Range, passing the town of Bukit Tinggi along the way.

[1] However, the road's very sharp corners, deep ravines, narrow roadway and lack of safety features made it dangerous.

Therefore, in the 1970s, a replacement segment for the narrow and winding Jalan Gombak from Kuala Lumpur to Karak was constructed.
