This is in Utah, USA and a mile long tunnel that is 1.6 km and was constructed in the 1930's to grant direct access to Bryce Canyon and Grand Canyon from Zion National Park. Since then was no big machine to dig so only mining techniques as opposed to traditional tunneling techniques.
No big trucks or large vehicles are allowed directly to the tunnel without giving an advanced notice and small cars have to pay some fees to pass as the tunnel was not built to big in diameter.

2. Eisenhower Tunnel, Colorado :

4. SMART Tunnel, Malaysia :

This tunnel is in Kuala Lumpur, Malaysia and runs 9.7 km long and is the world's longest multi functional tunnel. It was designed to reduce traffic jams and to alleviate flash flooding throughout the city as it have two parts, one with storm water drainage and other one for motorway.
So yes thus named SMART

5. Laerdal Tunnel, Norway :

This tunnel is in Norway and is 24 km long! yes we jumped to 24 straight form 9.7 km. It has two lane road and is The Longest Road Tunnel. Was built to replace the ferry and mountain passage during the winder. It was designed with special neon lighting and less straight lanes with making the ride more montony while passing through.

6. Guadarrama Rail Tunnel, Spain :

This tunnel is in Sierra de Guadarrama, Spain and runs 28 km long and was made in just 5 years between 2002 and 2007 and joined two heavily tourist spots of Spain. The tunnel first made travel time 1 hour run but now the tunnel services high speed railway trains, reducing traffic time to 30 minutes.

7. New Guanjiao Tunnel, China :

This tunnel is in Guanjiao Mountain, China and runs 33 km long and is dual bore, dual rail tunnel extending across the Qinghai Tibet railway. Is also one of the longest railway network part and seats above 10800 ft above sea level and took 7 years to complete.

With modern technology, we can excavate faster and smarter, resulting in massive network of tunnel that dramatically reduce travel time between location.

Timber Buildings !?

Timber Buildings !?  Why do we need a timber building? Yes, timber buildings. As on earth human population is on an exponential rise, many and many people are trying to get home in a city where they have easy excess for the workplace for their own living. In the near future, as the population gets more concentrated in cities more and more structures I mean Tall Structures need to be built. Loading Bearing and Comparison So now architects and builders have opted for old Technic of using timber as a building material eliminating concrete and steel. Yes, it is very hard to find this amount of trees but not impossible. It can be grown and regrown as needed. Many projects have been in progress of this idea and it reduces about 75% of carbon emission as compared to concrete and steel structure.

Using timber coming directly from the forest doesn't have the appropriate strength required for a high rise building. So designers came up with the new idea of CLT i.e. Cross Laminate Timber which …
