Sweden is prototyping an electric highway for trucks. It'll make transport cheaper and less damaging to the environment.
This specific effort is urban deliveries, 120 miles should be way more than enough.

You'd need much denser pantograph networks than any I know of for debatable benefits since the vehicles would still need the ability to go "off-network" (to enter private premises for instance). And for longer ranges, you might as well just use trains.
A gas tank with barely enough gas for 120 miles would work, but a battery for 120 miles can work only if you can quickly, easily and safely swap the batteries in your depot.
A Tesla Model X (5000lbs/2500kg) pulling a 5000lbs trailer uses about 700Wh/mi. If you assume 1kWh/mi for a small delivery truck, you'll need a 120KWh battery.
ChaDeMo chargers are ~62.5KW, Tesla Superchargers are ~135KW and future level 3 chargers could go up to 300KW.
So 12.5-25% of an 8hr shift. I would guess that would be unacceptably long for a large number of transport operators.
All that said, I don't think electric semis make much sense for long-haul trucking. That market would be much better served by electric trains. What does make sense is using smaller electric trucks and vans for local deliveries and waste pickup.
It would be, except for how difficult (right of way) and expensive it is to expand the rail network, and the extra work in moving between modes (since the last mile will be truck anyway).
Adding pantographs or inductive or something to for trucks to use on existing highways would be a lot cheaper and quicker to scale up than expanding rail.
I'm sure plenty of trucks drive more than 120 miles in 8hrs.
Particularly when major energy consumption patterns, and transport especially, have been studied to death. There's exceedingly good data out there.
Thanks from me as well for turning that up.
I could realistically assume that you're driving only 2/3 of the time at average speed of 30 mph... and that comes out at just 240 miles per a full day, and you could get a partial charge during e.g. lunch break, so if the battery was just a bit larger, then it's actually feasible.
With good DC charging, you should be able to count on adding 50% of your battery over a 30-minute lunch break, so if you do 240 miles in a day, your battery pack would need to be able to handle 160 city miles. Less if your truck is idle more or if it could charge more.
Right, there's only a 126 mile maximum range on that truck. So you'd have to stop and get a new battery every 2 hours, minimum on the interstate.
