I-10 is girdlock from exit 16 in Hancock County to the Mobile tunnel. Traffic was also reportedly very heavy on US 90 eastbound.
MDOT could do a better job updating their website:
MDOT has not entered any traffic alerts related to this event at this time.
They do have this press releases:
Due to evacuations that are in place due to Hurricane Gustav and contraflow operations that have been activated, below is a status update on the following interstate highway systems in Mississippi.
- Interstates 59 & 55 are being contraflowed at this time and traffic is posing some delays.
- There is a major traffic delay at Interstate 59 at Meridian.
- Interstate 10 into Alabama is open and flowing adequately.
- Highway 49 is open with moderate delays.
- Interstate 20 near Meridian has traffic delays.
Then they link to an empty press release saying to avoid I-10 eastbound:
MS Highways 15 and 57 to MS Highway 26 east to Lucedale and MS Highway 63 to Lucedale and Highway 98 will take you to north Mobile and I-65.
If you are headng North on MS Highway 603/53 to Poplarville consider going into town and taking US Highway 11 to Lumberton and MS Highway 13 to Columbia and eventually Mendenhall.
The bottom line is the line to get through the I-10 tunnel in Mobile is very long.
I just heard from a friend who is on Hwy 26 in George County that tells me there is heavy eastbound traffic but it is moving at the speed limit of 55 mph with the exception of a 10 minute bottleneck at the traffic light at the crossing of Hwys 57/26.
Another friend tells me traffic on Hwy 603 northbound is light north of I-10.
