Lingkaran Tengah Utama Expressway, previously known as Central Spine Road (CSR) or Kuala Krai–Kuala Pilah Highway, Federal Route 34, is a new toll-free highway under construction in the center of Peninsular Malaysia. The 325 km (201 miles) highway is built to eventually replace the former two-lane Malaysia Federal Route 8 (Gua Musang Highway) and Malaysia Federal Route 9 (Karak–Tampin highway). Construction of CSR starts at Package 3 which is from Merapoh to Kampung Relong. It commences at Package 3 as the Gua Musang Highway passes through Chegar Perah which is prone to roadkill. The highway has a long eco-viaduct built in this section. Package 5 which is from north Raub to Karak will be built next, which will connect it to E8 Kuala Lumpur–Karak Expressway bypassing Bentong and Mempaga. This will help detour traffic from the steep mountainous grade between Raub and Bentong. It was formerly known as Central Spine Expressway.
