Trucks with bridge beams affect traffic March 20-24

Next week on Monday through Friday, concrete bridge beams will be delivered at the Southwest Bypass bridge site in southwest Georgetown. Delivery of 120 precast bridge beams in convoys of six trucks at a time will lead to brief road closures on SH 29/University Avenue and on Leander Road at their intersections with I-35. Traffic on the main lanes of I-35 should not be affected. The beam delivery schedule is weather-dependent.

On March 20-22 from 9 a.m. to 4 p.m. each day, there will be closures of approximately five minutes in duration on University Avenue at the I-35 intersection. During each closure, Georgetown police will stop traffic on University Avenue to allow for the passage of six trucks carrying 120-foot-long bridge beams. After clearing the intersection, trucks will travel west on University Avenue and then turn south on D.B. Wood Road to reach the bridge site.

On March 23-24 between 9 a.m. and 4 p.m. each day, police will close Leander Road at the intersection with I-35 for brief periods to allow groups of six trucks with beams to pass through the intersection. These trucks will travel west on Leander Road and turn north at the Southwest Bypass right-of-way, which is about 600 feet west of Riverview Drive.

Once at the bridge site, each beam will be lifted from the transport truck with two cranes and lowered into place on bridge supports. The steel-reinforced concrete beams are for bridges over the South San Gabriel River and an unnamed tributary that are part of the Southwest Bypass project.

Due to the intermittent closures on SH 29 and Leander Road, drivers should expect traffic delays. Prior to moving through the SH 29 and Leander Road intersections, the trucks will be staging along the I-35 northbound frontage roads in Georgetown.

Southwest Bypass is a new north-south arterial that will connect with D.B Wood Road and Leander Road. The construction contract for the Southwest Bypass has a completion date in late 2018, however the contractor is ahead of schedule.

Street Sealant Work Update

On Thursday April 28, City crews will be applying black sand to the cul-de-sac on River Rock Drive in order to stabilize the Rejuvenation Street Sealant applied in March.  At approximately 3:00 p.m., as the temperature warms and the sealant softens, staff will apply a thin layer of sand and roller compact it into the street.  On Friday morning, crews will sweep any excess sand and monitor conditions as traffic drives on the roadway.

If the sealant is stabilized, crews will schedule the same application early next week when temperatures are expected to be high enough to activate the material on the following cul-de-sacs: Cobalt Cove, Tea Tree Cove, Cider Orchard Cove, Butter Fly Cove, Rainwater Cove, both cul-de-sacs on Stardust Lane, and Tipps Court.  Following the application on the cul-de-sacs, staff will continue to monitor the streets and intersections for any other reactivation and possible sanding application.  Staff will begin driveway cleaning once the sanding application is completed.

The sealant is used to fill small cracks and prevent oxidation of the road surface to extend the pavement life.  The recent tracking of the sealant in Sun City is the result of the latest applications not curing as rapidly as they have in the past. Tracking began occurring mostly on warm days as pavement temperatures reached 120 degrees, causing the sealant to reactivate. This caused tracking issues into driveways and onto adjacent streets.

Staff has shared this issue with the product manufacturer, and requested a plan of action to prevent further tracking.  The manufacture recommended using dry “blotter sand” to prevent additional tracking.  The sand should adhere to the remaining surface and provide a barrier between the surface and tires.  The City’s contract engineer has suggested following a typical TxDOT maintenance procedure for applying the sand.  Sand will be applied with a truck mounted sand spreader and rolled in with a pneumatic roller.  Once dried, any remaining sand will be removed using the City’s vacuum sweeper.  A black sand will be utilized to blend with the existing road surface.  This application will be performed during the warmest part of the day, when the product is reactivated, so the sand will set with the product.

Transportation Department crews have conducted tests in a vacant subdivision near Interstate 35 to help identify issues leading to the product’s tracking.  Staff performed the sanding procedure on freshly applied sealant in a small area with promising results.  Staff has also applied this application to a small test section in Sun City with similar results.

City crews are monitoring the sealant area daily, and have noticed tracks in the product when temperatures rise and heavy vehicles travel the roadway.  To minimize tire rubber and product tracking, residents should refrain from sharp turns into and on driveways.

No further rejuvenation street sealant applications are scheduled at this time.

Street Sealant Work in Sun City: Updated Dec. 7

Update, Dec. 7: The street sealant work in Sun City has been hampering residential seasonal shopping traffic and local parcel deliveries.  To reduce disruptions, City crews will be finishing the roadways already started and suspending further sealing until after the first of the year. Existing work should be completed by Wednesday, December 9. (See the updated schedule below.)  The sealing will be resumed in January when disruption to residents and crews will be minimized. Notification of the new schedule will be provided after the first of the year.

Below is the schedule for the sealant work, which will happen from 8 a.m. to 5 p.m. each day. Rain may cause changes to the schedule. The attached color-coded map (below) shows the sections that correspond to the dates.

Date: Section on map Neighborhood numbers
Monday, December 7 Section 2 40, 41, 43
Tuesday, December 8 Section 2 41

The sealant product, also called a rejuvenator application, seals the pavement and slows the oxidation process, extending the life of the pavement. The sealant treatment helps to defer more costly maintenance work.

Look for warning signs and flaggers who will be stationed throughout the neighborhood to provide residents with directions. The sealant will be applied to one half of the road at a time. Once the first half has dried, the second half of the roadway will be treated.

Each application typically takes 30 minutes to an hour to dry. High humidity may extend the drying time.

Crews will work to minimize disruptions during the sealant application process.

Driveway Access Affected:  A small orange cone will be placed in each driveway to signal that the sealant has been applied on the street and is in the 60-minute drying process. Residents should avoid driving on the freshly-applied sealant until the driveway cones have been removed. Flaggers will be present to give instructions on temporary parking locations while the sealant is drying.

Schedule changes: This schedule could vary due to rain, other weather conditions, equipment failure, or product availability. The City will update this schedule if there are changes.

Questions about this street work should be directed to Georgetown Utility Systems Customer Care at (512) 930-3640.

Street Resurfacing August 6 – 21

Street resurfacing with a chip seal treatment on several Georgetown roads is scheduled for August 6 – 21 in the area south of University Ave as shown in the map.

Chip seal resurfacing involves applying a layer of emulsion to the roadway followed by a layer of small-sized gravel. Unless otherwise noted, the entire length of the roadway will be resurfaced.  The chip seal wear surface will extend the life span of the asphalt on the street by slowing oxidation and sealing cracks in the asphalt. This will also help defer costly street reconstruction.

Chip sealing operations will begin after 7:30 a.m. and will end by 5 p.m. each day. Look for electronic message boards or door flyers in the neighborhood with information about the resurfacing schedule.

This schedule is weather-dependent and could be changed if there is rain.

Drivers should expect delays and look for flaggers in a moving work area. Drivers should reduce their speed and increase the spacing distance between vehicles to reduce problems with loose rock on roadway.

Following the application of the chip seal, street sweeping will occur within 24 to 48 hours to sweep up any loose chips. Once the sweeping operation has been completed a sealing material called Fast Set will be applied to the chip seal surface. The Fast Set sealant will require a drying time of 20 to 30 minutes prior to being open to traffic.

The sealant will improve the driving surface and increase protection from the weather. Public notification about the street sealant work will be done before work starts.
