Update 42-3: The Beltway (continued)

Update time!

Part 3 of my extremely long for some reason beltway update deals with the northeast section of the new beltway.

After the Transcontinental Freeway interchange, the beltway proceeds to curve northeast, north of the newly constructed stadium complex. There’s no special interchange for the stadium, though if there is a need for one, there is plenty of space to fit ramps.

Exit 11 or 12:

A simple diamond with the now 2 lane Government Pkwy is all that’s planned for this interchange. Traffic levels are low enough now that this is all that’s needed at this point.

After exit 11/12, the freeway proposal diverges into its second pair of route options. The preferred option continues northeast, while the alternate option swings back southeast.

Option 2a makes it way toward NH 192.

Exit 12/13:

This interchange, besides providing access to and from west NH 192 from the west on the beltway, it also provides local access to Gateway, the airport industrial area and cargo loading depot. The road here (Gateway Av) will be upgraded to a divided highway at the interchange.

Exit 13/14:

This is where the beltway/NH 192 multiplex begins. The exit provides access to Airport Blvd for the rail station, parking facilities and hotels, as well as an alternate route to the airport. The interchange is rather unorthodox, having NH 192 merge with the beltway in the middle. But traffic levels are projected to be divided rather evenly between the beltway and NH 192, enough so that this setup is acceptable. The other reason for this will be discussed a little later.

Exit 14/15:

This exit… is already built, in its entirety. I’d show a picture, but there’s no point considering nothing about it is changing except some widening on the beltway portion. This exit, of course is the main access point to the airport, it being the terminus of I-302.

I mean I suppose I could show a pic...

Exit 15/16(clockwise):

This is the reason NH 192 is allowed to enter and exit on the left at exit 13/14. The multiplex is only for the I-302 interchange… As with the western interchange, NH 192 exits and enters on the left. This interchange also provides access to northbound I-5 for eastbound beltway drivers.

Exit 15/16 (counterclockwise):

The beltway begins its multiplex with I-5 at this point. The interchange is a simple fork, with priority given to I-5.

Exit 16/17:

The current situation is an at grade junction with Rt. 7. That would be changed to a diamond interchange.

Option 2b travels farther south of NH 192, effectively forming a bypass of Gateway and Sunnysidington.

Exit 12/13:

option_2b_exit_12_or_13.png

A simple folded diamond.

Exit 13/14 A-B-C-D:

option_2b_13_or_14_abcd.png

By far one of the longest stretching interchanges in the proposal, this interchange will provide access to the Airport Expwy as well as I-302. Full access is provided between all roadways.

Exit 14/15:

This t-bone interchange will provide access to both directions of I-5. Priority is given to I-5.

One more part to go, I promise. Then we can get to the fun stuff.
