I-10 work in July: updated timeline

Welp, we're midway through July. That takes us through the activities (well, most of them) noted on our earlier post detailing the work along I-10 between San Antonio and Boerne. Here's an updated timetable from our project engineer:

At Scenic Loop Road
In order to demolish the old westbound I-10 bridge over Scenic Loop Road (traffic was switched off the bridge in earlier weeks) we'll have the intersection under I-10 closed through this weekend.
Work will begin Friday (July 14) at 9 p.m. and wrap up no later than Monday at 6 a.m.
Traffic from Scenic Loop Road and from Cascade Caverns will use the frontage roads and turn around at either Business 87 or at Balcones Creek to reach its destination.

New overpass at Old Fredericksburg Road
The eastbound main lanes will be moved onto the overpass this weekend. Sundt Construction will start around 3 a.m. Saturday (July 15) and continue until finished - no later than Monday at 5 a.m. We'll keep one lane of I-10 open, so we're not shutting the highway down, but expect slow going. When we're all done Monday we'll have eastbound lanes all up on the new overpass bridge.
That means the westbound side will get done the following weekend (July 22-24), following the same schedule. To be clear, that's 3 a.m. July 22 until 5 a.m. July 24.
With traffic  up on the new overpass we'll have crews working to open the intersection below - which will happen early 2018 - before converting frontage roads between Ralph Fair Road and Old Fredericksburg Road to one-way.

New westbound exit to Hwy 46
The new westbound exit ramp to Hwy 46 is finally opening up, but we'll have to use some closures to make it happen. That work wills tart 9 p.m. July 28 and run through 5 a.m. July 31. When we're finished we'll have the new westbound frontage road fully functional, including a new westbound exit ramp to Hwy 46 and an on-ramp serving those coming off the frontage road.
During the ramp closure traffic will use Business 87 (Main Street) and Hwy 46 (Bandera Road) to reach its destination. This route will be posted with signs as appropriate.

Next major thing at Fair Oaks Parkway
The next major closure of I-10 at Fair Oaks Parkway will be the granddaddy and is tentatively scheduled for August 4-7. We'll be demolishing the old Fair Oaks Parkway bridge, which will take a long time to get done. Why? We lay down a bed of sand and dirt on the road to cushion the main lanes against falling chunks of concrete, then break away and demolish the bridge, then clean up the debris, then clean up the sand/dirt bed we laid down. It takes a good minute to get done.
Before we do that, we'll be shifting traffic off the current bridge onto the new turnaround bridge; that turnaround bridge is wide enough to accommodate traffic the same as the current bridge does. This is a temporary shift until the full project is complete.
We'll have more info on this work in upcoming posts.
