Why does KEWR have straight taxiway intersections, as opposed to curved?
 

I thought my flight sim had modeled it wrong, but it turns out that Newark has corner taxiway intersections instead of what I assume is the standard curved. Why is this? kewr - Google Maps

There are several high speed exits along the runway. If you get to the end of the runway, you should be going slow enough to make a 90 degree turn.

Other airports have similar layouts and don't have these straight lines. Is it just cheaper to do away with curves?

Lost with the terms
 

Nice google map of the KEWR runway and taxiway layout!

I am afraid I do not understand what you are asking.

The link takes me to a picture of two runways at KEWR. The curved taxiways are high speed exits or turnoffs to be used when landing from the opposite direction. They are curved by design to allow the aircraft to exit at a slightly higher speed after landing than would be required if they were at 90 degrees to the runway. This makes more efficient use of the runway, than requiring everybody to slow down to a crawl to make the 90 degree turn. We can safely get off the runway in less time.

The paint, markings, signage and lighting all communicate information under different environmental conditions and type of airport operations conducted.

Of course the same curved taxiways are used for departing aircraft as they enter the runway prior to takeoff. Taxi speeds are slower when entering the runway (normally). They don't "need" to be curved.

Sorry for not understanding your question better. .

Curved lines are very expensive and it is easier and cheaper to use straight lines. For a start you just need a set square not a compass with one of those pencil leads at one end.

Was EWR originally a military airfield? Military airfields often have 90 degree turnoffs.

I don't really understand the question, but as you can see, taxiways alpha and bravo curve. Numerous other taxiway intersections meet at various angles. The edges where they meet are curved, or radiused.

I meant straight taxilines.

You mean the taxiway centreline markings meet at right angles instead of joining together in nice curves, which does look a bit odd especially where taxiways C and N meet ?

Yes, centerlines.

Plenty of the centerline stripes at both LGA and JFK tee at 90 degrees. I don't think there is anything odd about it.

All three of those airports are run by the New York Ports Authority. Perhaps curved lines aren't very nautical!

As for the question, should the Ports Authority be running airfields, all I can say is that as for operating from them, particularly ground operations, JFK and EWR were two of my least favourite destinations when I flew long haul.

Port Authority manages the airport, but air traffic and ground operations are performed by the FAA air traffic control.

Being a "Port Authority" is just a US bureaucratic workaround for a public body which crosses state boundaries, in this instance both sides of the Hudson embracing New York and New Jersey states. It appears that other types of public ownership, unless by the Federal Government itself, are not possible which cross state boundaries. The one in New York does all types of transport - the airports, bus terminals, bridges, some subway lines, harbour installations, etc.
