First one that comes to mind is a bridge/tunnel between the islands of Dazhitou and Daishan connecting Shanghai with Ningbo and Zhoushan. It would save you over 2 hours of driving.

Norway is replacing its ferries on the costal E39 highway with bridges and tunnels, not sure what the time savings will be, but I assume it will make a big difference.

Another important project is the Brazzaville-Kinshasa Bridge.

Fist one that comes to mind is the Dublin to Holyhead (Wales) tunnel which has been talked about for years.

They'll be talking about that for many more years. Not enough traffic to justify cost.

There are some crossings that are politically avoided. India / Sri Lanka once had a crossing, which has been abandoned. Morocco / Algeria have modern highways right up to each other, but no crossing for decades. The Congos, one chaotic ferry crossing a day. Suriname and Guyana, 15 minutes by ferry, once a day. Panama will never develop a land link to Colombia through the Darien Gap, which is an efficient livestock quarantine.

In America, feasible ferry crossings have failed: Toronto to Rochester, or Milwaukee to Michigan, avoiding Chicago.

In terms of London, the Silvertown Tunnel and the Lower Thames Crossing are the future big projects, whilst there is also plans for a tunnel near Stonehenge in South West England.

There have been proposals to link the Isle of Wight to the mainland, as well as a tunnel to Ireland and proposals for a tans-pennine road tunnel linking cities in North West England, however most British tunnels in recent years have been rail and Utilities.

The Channel Tunnel. HS1, Northern Line Extension, Thames Tideway Tunnel, Elstree to St. John's Wood Cable Tunnel, Crossrail, HS2 etc are recent examples of rail and utility tunnels.

In terms of road tunnels, as well as the Silvertown and Lower Thames Crossing there are plans to ease traffic on the A27 through the construction of a new tunnel, whilst the longest recent road Tunnel is the Hindhead Tunnel in Surrey, a 1.1 mile (1.8km) tunnel, on the London-to-Portsmouth A which was opened in 2011.

Tunnelling Work Has Started On The Controversial Silvertown Tunnel - Londonist (5th October 2022)

The longest road tunnel in the UK, is currently the Queensway Tunnel beneath the River Mersey in Liverpool and is 3.2km in length, which is around 2 miles, however the Lower Thames crossing is set to be 2.6 miles (4.2 km) long, whilst the new Stonehenge tunnel is set to be 1.3 miles (2.1 km).

Transport for the South East (TfSE) recently announced proposals for the £2bn, 4km-5km A27 diversion tunnel as part of draft Strategic Investment Plan for the South East England, with other proposed projects including a a £3.2bn extension of the Elizabeth line (Crossrail) to Ebbsfleet and beyond to Gravesend, as well as a proposal for a £4bn underground line to connect Southampton and Portsmouth.

Plans for UK’s longest road tunnel backed to ease congestion in south east - New Civil Engineer (September 2022)

Crossrail saw 26 miles of new deep rail tunnels, HS1 saw 16 miles of new rail tunnels and HS2 is currently boring 64 miles of new rail tunnels and collectively this amounts 106 miles of new rail tunnels without even counting the 30 mile Channel Tunnel.

HS2 -Tunnels

HS1 -Rail Technology

As for the Thames Tideway Tunnel (water utilities) it stretches for over 16 miles (25 km)

As for the Sheffield to Manchester Trans-Pennine Tunnel that is currently on hold, so will not be going ahead in the foreseeable future.
