Weigh station east of Kewanee Truck scales $3.91 million


At US 11 in Hattiesburg PE for interchange reconstruction $100,000

Froggie's Notes:

- Although maligned by some, I-59 serves as an important connector.  It would be my route of choice from New Orleans to the Northeast, utilizing I-75 and I-81, as it allows one to avoid the traffic of Atlanta and along I-95.
- The first sections of I-59 opened in 1963, across the Pearl River and between Hattiesburg and Laurel.  By 1969, I-59 through Mississippi was complete, except for the duplex with I-20 through Meridian which wasn't upgraded until the mid-70s.
- Although not signed as such from the Interstate, the Kewanee exit (Exit 169) is also US 11/80.

Froggie Suggests:

- Widen to 6 lanes from US 98 East to US 49 near Hattiesburg.
- Consider the feasibility of adding an interchange somewhere between US 11 and US 98 West near Hattiesburg.
- Full reconstruction between US 49 and US 11 northeast of Laurel to replace deficient pavement and geometrics, including the 40 MPH "S-curve" in Laurel.
- Add auxiliary lanes between interchanges in Laurel.
- Widen to 6 through lanes plus auxiliary lanes from I-20 West to US 45.
- As an alternative to widening through Meridian, an Interstate-grade southern bypass of Meridian could be built instead, from near Lost Gap east to the existing US 45 South bypass.  I have dubbed such a bypass as I-259.
- Interchange improvements and ramp additions as needed.
