Gas tax increase to finish Nebraska's expressway system?

The York News-Times has had a couple articles regarding a proposed five cent gas tax increase to finish the expressway system in Nebraska.

A map of the planned expressway system can be found on page 35/39 in Nebraska's 2006 highway needs assessment.

A rough map created to show an earlier, much more ambitious expressway/freeway plan for Nebraska can be found here.

Given the current rise in gas prices, I would not expect this to be popular with many voters. Furthermore, some of the projects should be reevaluated. Unlike Kansas, expressways in Nebraska are limited to 65 mph, the same as many two lane US routes are posted at in western Nebraska already. In addition, traffic on some of the routes is extremely low; parts of US 385 saw less than 2000 vehicles a day back in 2008. Conversion of US 385 to a shared four lane should be much cheaper.

Two comments on the 2006 Needs assessment as long as I've brought it up:

1) The expressway system map lacks the NE 50 expressway from south of I-80 to Springfield.

2) The plan lacks any mention adding interchanges to the US 281 Grand Island - Hastings expressway. Given the number of stoplights along the west side of Grand Island, and a lack of apparent coordination, this route is no longer 'express'. There is also a stoplight between I-80 and Hastings at Doniphan that should be replaced with an interchange. Of course, Nebraska has never been good with consistency on their expressways - witness the how US 77's expressway sections pass through Cortland, Princeton, and Ceresco instead of bypassing them.
