The project of the water hole interchange area of the Huan Expressway is taken with the photo

The water hole interchange service area of the Sanjialing section of the Benhuan Expressway is the four interchange areas of the Benxi County section; That is, one of the water cave interchange area, the small city interchange area, the Tianfu interchange area, and the alkali plant interchange area, its engineering quantity and complex structure should be ranked first. Since the start of the entire project in August 2022, the author has passed by here many times, and has been paying attention to the progress of the project here.

In addition to the large amount of engineering and complex structure, there is also a difficulty in this interchange area project, which is located next to the old highway with busy traffic, and the construction and traffic will interfere with each other, which is a big problem, which is a great test for the project and traffic safety.

These two pictures are satellite photos combined with engineering schematic diagrams, and the "twisted strands" like lines in the pictures show an intricate situation, and it is indeed difficult to carry out construction in the mountains and ravines.

This is a photo I took here in September 2022, before construction began.

This was in April 2023 last year, and the site was cleared before construction began.

This is the construction site photographed in August 2023 last year.

The "door face" was erected

This is now the progress of the works in May 2024, on the north side of the ditch.

At the main entrance, it can be seen that the traffic is a little congested.

The exit of the Sanjialing Tunnel No. 1

The exit of the No. 1 tunnel of Sanjialing is very hidden here, and it is difficult to find it without approaching.

The construction site here is complex, the structure is compact, and there are many construction machinery and vehicles in the construction site, it is difficult to find a suitable location to shoot here, and to ensure their own safety, and to achieve the goal, and not to be driven out, it is necessary to be very low-key, have eyes, and have wisdom to find an important position, you don't ask the best, ask but be questioned, to be honest, it is not easy to be a "spy"!

Finally, with a keen "sense of smell", I found the "entrance to the No. 2 tunnel of Sanjialing" that I had been paying attention to but had not seen.

It is hidden in this small mountain col, which cannot be seen from the outside, and the exit over there is in Luoquangou in Moshiyu, which is the first to start, and this side is much later.

What's more important is that I saw the master plan of this interchange area here, which I had never been able to find.

The master plan of the whole road

Thank you for your attention!
