I noticed that Google Maps has been updated to show a northward extension of SH 289.
It used to terminate at SH 56 (OLD US 82), but now has been extended north to a terminus at a county road near Lake Texoma; with no possibility of being connected to anything. It makes sense to extend SH 289 up to US 82; to me that should have been done when US 82 was realigned. However, the only value of continuing the SH 289 designation up into the lake area is 1) Route number continuity and 2) Funding. It seems a little odd that a State Highway ends at a county road with no chance for extension.

It could be a mapo. Google maps is full of them.

It's no mapo. The Highway Designation Files were canged in 2009 to show this change.

There is a bit of a mapo involved; I checked into what Google Street View shows and the state maintenance stops at the Elks Road turnoff (http://g.co/maps/2fbh7) across from Island View Park. The picture still shows FM 120 signage since Google hasn't taken a Street View trip up there since before the TX 289 extension (and FM 120 replacement north of Pottsboro) was completed. The rest of the road up to the end at Preston looks to be county or locally maintained.
From what I can tell, the TX 289 extension directly benefited North Texas Regional Airport, Pottsboro, and the Tanglewood resort (whether they had a hand in trying to get TX 289 extended or not).
There are many FM/RM roads and a few primary TX state highways that don't end at another numbered road. Unusual, sure, but not rare.
Here's the link to the Highway Designation Filehttp://www.dot.state.tx.us/tpp/hwy/sh/sh0289.htm (http://www.dot.state.tx.us/tpp/hwy/sh/sh0289.htm)
The news story does state taht local official wanted the extension to benifit development in hte Airport area.
I got bored last year (I was supposed to go to a kid's birthday party in Frisco but just kept going) and drove all the way to the end of 289. There wasnt a very visible end to it. One thing I did notice, though, is that the official TxDot state map doesnt show the extention at all.

From what I understand, part of the new extension of 289 will eventually become an extension of the Dallas North Tollway. Part of the money used to build it came from the NTTA. Of course, that is decades away. The DNT main lanes end at U.S. 380 and one future frontage road is built out to FM 428 in Celina.
