Froggie's Notes:

- I-10 is the primary east-west Interstate across the southern U.S.  Within Mississippi, the route was generally built about 5-10 miles inland, both because of existing development along the coast and to facilitate hurricane evacuation along a route that would be less likely to flood over due to its inland nature vice a more coastal routing.  This feature became evident during Hurricane Katrina, where most of the post-hurricane problems along I-10 simply involved debris removal.
- At its closest point (just west of I-110), I-10 is still 4 miles away from the beach.
- Although I-10 was planned in the late 50s-early 60s, construction of it was slow compared to the other Mississippi Interstates.  The first section to open wasn't until 1966, and that was a paltry 2 miles from Exit 75 east into Alabama.  There are many swamps and bayous along the coast, and the environmental sensitivity associated with them is what hindered construction.  The last section near Pascagoula wasn't complete until the early 1980s.
- The route carries a considerable amount of traffic, both regular and truck traffic.  Because of this, various business and commerce proposals have called for expanding I-10.  Combined with traffic increases as a result of opening casinos along the Mississippi Gulf Coast, the Mississippi Legislature authorized parts of I-10 to be included in the Gaming Roads Program.  This program has resulted in the 6-laning of I-10 between Beatline Rd (Exit 28) and I-110/MS 15, as well as the planned widening east to MS 57.
- Although not part of the Gaming Roads Program, the segment between MS 43/603 and Diamondhead was recently widened to 6 lanes.  The main driving force behind this widening was the need to replace the bridge across the Jourdan River.

Froggie Suggests:

- Provide a minimum of 6 lanes through the state of Mississippi.
- Widen to 8 lanes between US 49 and I-110/MS 15.
- Auxiliary lanes between the interchanges at MS 613 and MS 63.
- Interchange improvements and ramp additions as needed.

I-10 crossing the Pearl River, where the Louisiana/Mississippi state line is located in this area.

I-10's interchange at MS 607 is in the bottom center of this image.

Just east of the I-10/Canal Rd (Exit 31) interchange.  This is the general area where MDOT wants to build a freeway-to-freeway interchange as part of a project to build a freeway connector between I-10 and the Port of Gulfport.  The proposed connector is officially listed as Future MS 601, although some recent planning documents have also referred to it as I-310.

The I-10/US 49 interchange in Gulfport.  I-10 runs left-to-right, US 49 runs bottom-to-top.  There are traffic signals on US 49 at the bottom (Creosote Rd) and top (Landon Rd) of this image that are major bottlenecks along US 49.

The I-10/MS 67 interchange, technically located in Biloxi (yes, Biloxi's city limits extend north of I-10 in some places).  Two changes here in the future...first, MS 67 will be relocated onto a new-alignment 4-lane highway with a new southern terminus at MS 15, about a mile north of the I-10/I-110 interchange.  Second, when/if MDOT gets their proposed "East Harrison County Connector" built, this interchange here will morph into a combination diamond and freeway-to-freeway interchange, with the connector running to the south.

The I-10/I-110/MS 15 interchange in D'Iberville.  I-10 runs left-right, I-110 runs south from I-10, while MS 15 runs bottom-to-top through the interchange.  A westbound C/D road keeps traffic on the heavy NB-to-WB loop from weaving on the westbound mainline.

I-10 (and US 90 just to the south) at the Mississippi/Alabama state line.  The thin white line running from top-to-bottom marks the state line.  Notice the small clearing, located between I-10 and US 90 opposite the westbound weigh station.  Prior to I-10's completion in Mississippi, that clearing was the location of a connection between the 4-lane US 90 in Mississippi and I-10 in Alabama.
