It could be a vital piece of underground infrastructure you use every day, or a project you are helping to design or build.
And it doesn't matter if you can't get to an actual tunnel – be creative, as long as your photo gives an insight into tunnel engineering and helps the public understand the work of civil engineers.
How to get involved
Here's how to share your love for tunnels and be part of a movement to inspire the next generation of engineers.
- Post a picture of yourself inside a tunnel anywhere in the world
- If you can, include the name and location of the tunnel
- Include the #tunnelselfie hashtag
- Tag ICE (Twitter and Instagram: @ice_engineers | Facebook: @institutionofcivilengineers)
The best of these "tunnel selfies" will be shared through our social media channels and displayed on screens in the Tunnel Engineering exhibition or on the website.
Wherever you take your selfie, remember to stay safe and follow any guidance from your employer or client.
Inspire future engineers
By taking part you'll be helping to get visitors to our next exhibition excited about what civil engineers do.
Since October we've welcomed 10,000 people through the doors of our first exhibition on bridges, including school groups, families and students. The online version has also had 30,000 visits.
You can see some of the bridge selfies people sent in on the Bridge Engineering exhibition web pages or on Twitter.
How to visit
Tunnel Engineering opens in mid-May 2017 in the Infrastructure Learning Hub at ICE's One Great George Street home in Westminster, London.
The creation of the Infrastructure Learning Hub is supported by 11 founding partners: AECOM, Atkins, Carillion, Costain Ltd, Kier, Mace Foundation, Mott MacDonald, VINCI Construction UK Ltd, WSP | Parsons Brinckerhoff, Ramboll and John Laing.
The exhibition will run for six months and more details on exhibits will be announced shortly. Until then, happy selfie snapping!
