New Milestones Reached across Multiple Motorway‑building Schemes in Yunnan

According to Xinhua News, several major expressway projects under construction in Yunnan have hit key construction milestones in recent weeks, pushing forward the regional road‑network expansion across the mountain‑fringed province.

Work on the Fuyuan‑Luoping motorway has registered notable progress on two bridge structures. The last of 155 pre‑stressed T‑beams has been fitted for Kuaze River No 1 Bridge, which stretches for 638.08 metres in total. This marks a vital breakthrough for the main bridge works along the route. Over at Xiaodeke Bridge, all 70 pieces of 30‑metre prefabricated T‑beams have been successfully placed. Each single beam can weigh as much as 86.71 tonnes, clearing the way for subsequent deck surfacing and ancillary civil engineering tasks.

Further west along the Yunlong‑Yongping expressway, Jiapeng No 1 Tunnel has been fully broken‑through. Measuring 565 metres in overall length, this tunnel reaches a maximum overburden depth of roughly 87.86 metres. Its completion unlocks the building sequence for the nearby Jiapeng interchange, creating favourable working conditions for follow‑up roadbed, bridge and auxiliary construction activities.

Construction crews are racing towards the opening date for the Old Town of Lijiang‑Ninglang expressway. The ring‑road section of this scheme has now finished 99 per cent of its overall civil works. Subgrade construction stands at 99.9 per cent, bridge building at 99.7 per cent, while all tunnels have been opened on both carriageways. Once this ring segment comes into service, it will join with the Lijiang‑Huali and Dali‑Lijiang motorways to establish an outer orbital fast‑transport corridor encircling urban Lijiang. Through‑traffic vehicles will then be able to bypass the city centre, delivering more efficient connections between municipal urban road systems and the provincial expressway grid.

On the Yuanmou‑Dayao expressway, blasting and muck‑clearing operations have finished for the left tube of Jingfengkou Hill No 2 Tunnel. This twin‑bore short tunnel runs 310 metres for its right bore with a maximum rock cover of 78.7 metres, whilst the left bore extends to 318 metres with a maximum burial depth of 79.63 metres. The breakthrough lays solid groundwork for the remaining phases of on‑site building.

Prefabrication tasks at the No 1 beam‑casting yard for the Menghai‑Daluo motorway have been fully wrapped up, with the final 30‑metre pre‑stressed box girder cast in‑situ. Altogether 368 box girders have been completed at this facility. The casting yard occupies an area of 7,272 square metres with physical dimensions of 303 metres by 24 metres. On‑site equipment comprises two gantry cranes together with two smaller gantry hoists, alongside twenty pre‑casting pedestals. Completed beams from this yard will supply the subsequent erection phase for Mandanlong No 3 Bridge.

Additional civil engineering operations will keep moving ahead on these five Yunnan expressways in the months ahead. Continuous advances on tunnels, bridge superstructures and road‑bed sections will steadily bring these mountain highway schemes nearer to final completion, strengthening the overall road connectivity for south‑western China’s highland region.
