The tunnel is expected to be completed in 2026.
A few months after the opening ceremony, construction of the first tunnel on the D35 highway begins. The association of companies Eurovia CZ, TuCon (now Marti) and Eurovia SK started the excavation of the left tunnel of the future Homole tunnel near Vysoké Mýt.
The ŘSD reported about the transfer of jobs on social networks. The tunnel will be part of the Ostrov – Vysoké Mýto section. “We started digging in the left tunnel by demolishing the stone wall. Excavation will be carried out using the new Austrian tunneling method using tool disconnection and blasting when hard geological layers are reached“, the ŘSD reported the current situation.
The left tunnel will be 525 meters long, and the other 570 meters. On the left side, 180 meters will be excavated, the rest will be stamped. 120 meters will be dug on the right. The height of the overburden is between 8 and 24 meters. The I/17 road runs above the tunnel. The tunnel runs under the Vraclava Ridge.
Marti said on his website that the tunnel runs through challenging geological and hydrological conditions from Quaternary rocks and sediments to sandstone and limestone.
The construction of the tunnel will cost 1.754 billion crowns. The selection of the contractor was greatly delayed due to the objections of the company Metrostav TBR, which questioned the experience of the winning association.
The tunnel should be completed in 2026. The entire section Ostrov – Vysoké Mýto, about seven kilometers long, the road authorities want to implement in 2026. It will connect to ‘ part of the highway D35 Časy – Ostrov, which was opened last year last December. At the other end, the section Vysoké Mýto – Džbánov, which is already under construction, will connect to it. The tunnel is described in more detail in information sheet.

What are some of the specific environmental considerations that engineers need to address when excavating a tunnel through a sensitive ridge like the Vraclavský hřbet?
This text snippet seems to be part of a news article or blog post related to the construction of a tunnel (possibly the Homole Tunnel) on the D35 highway in the Czech Republic.
Here are some open-ended questions aimed at sparking discussion on the key topics:
**Thematic Sections and Discussion Questions:**
**1. Tunnel Construction:**
* What are the biggest challenges engineers and construction workers face when excavating a tunnel like this, especially through a ridge like the Vraclavský hřbet?
* How do environmental concerns factor into the planning and execution of these large-scale infrastructure projects?
* What technologies and innovations are being used in the construction of this specific tunnel?
**2. Local Impact and Benefits:**
* How will the completion of this tunnel impact the local communities and transportation within the region? Will it shorten travel times, improve connectivity, or create new opportunities?
* Are there any concerns from local residents about the potential downsides of the tunnel’s construction, such as noise pollution, traffic changes, or ecological impact?
*
**Economic and Infrastructure Development**
* How does this tunnel project fit into the larger picture of Czech infrastructure development? What are the national economic benefits of improving highway connections?
* What role does this project play in attracting investment and supporting regional economic growth?
**3. Public Engagement and Transparency:**
* How has the project been communicated to the public? What measures have been taken to ensure transparency and community involvement in the decision-making process?
* Are there any mechanisms in place for addressing public concerns and grievances related to the project?
By dividing your interview or discussion into these thematic sections, you can explore the multifaceted aspects of the tunnel construction project in a comprehensive and engaging way. Remember to encourage diverse viewpoints and critical thinking to foster a meaningful dialogue.
