First, your press release in incorrect. It states that west bound traffic can turn onto Gladstone Court. Currently, the entire entrance is blocked off. Which leads to the issue of emergency vehicles trying to wind their way through the subdivision (which is often difficult because of parked cars) to get to their destination. Finally, why wasn't the entrance to the Latera subdivision used? There are FAR fewer homes there and they have another entrance off Preston that could be used. Maybe because they are the "high $$$ homes"?
To have this arrangment for 6 months is unacceptable...and dangerous.

Jim,

We apologize for the difference from the press release. TxDOT originally planned to allow westbound traffic to turn into Gladstone. However, as TxDOT was setting up the traffic switch, they made the determination to not allow that movement in order to minimize confusion and maximize safety at the intersection.

The Fire Department was alerted in advance and is aware of the closure. Since the primary response for your neighborhood would come from the east, emergency vehicles can enter at Turf Lane and would not need to do any backtracking. In addition, if the Fire Department determined that they needed to enter at Gladstone Court, they can move the barricades.

TxDOT did not use the Latera subdivision entrance for the location of the traffic switch because Latera only has two access points. If the Eldorado entrance was closed, that would leave that neighborhood with only one entrance (on Preston in the middle of the construction). The City requires that neighborhoods have two points of access at all times, and so TxDOT chose to close Gladstone (because the Dominion neighborhood has four access points, three of which will remain open during the traffic switch).

We apologize for the inconvenience to your neighborhood and appreciate your patience as we undergo these growing pains. Once construction is completed, traffic conditions in the entire area will be greatly improved. Even now, the traffic switch that was made on Friday has allowed us to improve the efficiency of the traffic signal at Preston & Eldorado and westbound traffic is already benefitting with much lower delays. Any extra time it takes Dominion residents to get out of the neighborhood during this phase should be more than made up with the time savings they will experience at Preston & Eldorado.

As a followup announcement on this issue, the City has been talking to TxDOT about this issue and TxDOT has agreed to build a new crossover transition in the median east of Gladstone, which will allow them to reopen Gladstone. They estimate it will take two to three weeks to complete this work and reopen Gladstone.

Week 2 is nearly complete with no signs of starting on the crossover transition to reopen Gladstone. Anything holding this work up?

We have been working with TxDOT on the location and design of the cross-over. The contractor was going to start working on the cross-over Thursday, but rain delayed the start. Work should start today (Friday, 9/3) and the cross-over should be open by the end of next week.

With the lane switch, it seems like west bound traffic on Eldorado has been backing up to almost Turf Lane. To make matters worst, once you are on Preston, the light at Meadows Hill was causing another backup on Preston. I have noticed this happening between 745am to about 830am.
I have timed myself and it takes about 10 to 15 mins to get from Eldorado (from Tuft Lane to past through Preston).

Is there anything that the city and TXDot can do to relief the issue?

Thanks for all that the city do to make things better.

Mike,

We have been observing this area since the traffic switch and making signal timing changes at Preston and Eldorado and at Preston and Meadowhill. Our own observations have shown that over the course of a day, there is a time savings for westbound traffic on Eldorado compared to how the intersection used to operate (especially since through traffic and left-turning traffic no longer share the same lane at the signal). In fact, because more Eldorado traffic has been able to get past the Preston signal than before, that has led to more traffic reaching Meadow Hill and contributing to the backup you describe. However, there may be specific times of the day when the heaviest westbound traffic will continue to cause congestion on Eldorado in the construction zone. In addition, on any particular day, rain and/or a traffic incident can increase queues and travel times. We will continue to make changes in this area to try and address the congestion as much as possible given the constraints due to construction.

Now that the switch has occurred, the TxDOT contractor can start the intersection reconstruction. The completion of this work will be key to overall traffic improvements in this area. We continue to support TxDOT and offer to help them anyway we can so their contractor can complete the work in this area as quickly as possible.

Thanks

I realize we got 2 days of rain, but it is now 9/10 and still no work on the crossover. When will this be started?
Also, it appears no construction is being done at the El Dorado and Preston intersection...again. Why the start and stop method?

The previous post by Jason indicates that work was going to start on Friday 9/3. As of yesterday 9/12, I have not seen any such work. When do you think they will begin the cross-over?

Work on the new cross-over began this week after rain delayed work last week. The new cross-over, which was originally anticipated to be east of Gladstone, has been relocated between Eldorado and the Panther Creek bridge to avoid the removal of several trees and irrigation systems in the median. The existing curbs have been removed and the preliminary grading has been completed. The contractor is expecting asphalt delivery on Friday (9/17) or Monday (9/20) to pave the detour.

TxDOT expects to open the new cross-over next week, weather permitting.

When will they re-start work on the Preston/El Dorado intersection? Why is the construction so sporadic?

The construction of the Preston Road/Eldorado Parkway intersection is ongoing. The reason the construction may seem sporadic is typical construction sequencing. For example, at Preston/Eldorado, the contractor completed constructing the subgrade for the pavement at the intersection and continued the same operation on Preston north of Eldorado. The contractor does not typically want to schedule the next operation, placement of asphalt, until enough work is available for the sub-contractor to move in once and work continuosly on the project. Once the asphalt is placed, the reinforcing steel placement is scheduled, and finally, when there is enough work ready, the concrete paving crew is scheduled.

If you drive north on Preston from Eldorado, you will notice that the subgrade and asphalt are completed for the southbound lanes all the way to Rockhill Road, the reinforcing steel is tied at the intersection, and the concrete paver is ready to begin concrete paving. It may seem that the construction has been sporadic, but the crews have been progressing well on the project.

The right turn onto Eldorado from Preston is quite dangerous since the curb extends too far into the turning lane. I have seen cars routinely come really close to hitting cars waiting to turn left onto Preston. Is there something that can be done to remove a portion of that curb until construction is completed?

TxDOT is expecting to shift traffic to the north side of Eldorado Parkway next week. This traffic switch will allow the contractor to begin construction on the southwest corner of the intersection. When traffic is switched, the problem with the curb should be resolved.

As cars/trucks turn east (right) onto Eldorado from northbound Preston a hole is starting to form and its getting bigger every day as everyone rounds off the turn onto Eldorado. Can the contractor or the city put some asphalt there to smooth out the hole?

TxDOT has been made aware of the problem and will get it fixed in the next couple of days.

Also, TxDOT has scheduled (weather permitting) the traffic switch to the newly paved southbound lanes on Preston on Tuesday, 11/23. After the traffic switch, the temporary pavment should not be an issue.

It is nice to see good progress on the road work in Preston\Main\Eldorado area.
What is the planned timeframe for completion of preston road expansion from Main to Eldorado?

From what I gather they're going to tear up the east side of the road and repave it as well. Is there a time estimate (rough obviously) on how long that will take?

The current schedule shows that the Eldorado/Preston intersection will be completed in Summer 2011. The completion of the intersection somewhat relies on the completion of the northbound lanes that have just begun.

Is this intersection behind schedule now? The eastbound merge of Eldorado (westbound lanes) before Preston has not changed in 6 months.

Construction of the intersection has been delayed by conflicts with existing utilities; however, completion of the intersection is not yet behind schedule. It appears nothing has changed, but the next traffic switch cannot happen until the southeast quandrant of the intersection is completed. The contractor is constructing that quadrant concurrently with the construction of the northbound lanes between Main St and Eldorado.

We are still working with TxDOT to complete the intersection as quickly and efficiently as possible.

Traffic on Eldorado Parkway will be switched to the new pavement on the south side of Eldorado on Tuesday, May 10. This will allow the contractor to complete the intersection paving.

We are hoping to have the intersection completed by early July.

Why was a separate left turn lane not added for westbound traffic on Eldorado onto southbound Preston? It seems there is room, and there are as many cars turning left westbound as eastbound where there are two dedicated left turn lanes.

Albert,

A second westbound left-turn lane is planned to be constructed at the intersection. The widening of Preston Road is a TxDOT project and the widening of Eldorado Parkway to the east is an upcoming City project. The TxDOT Preston Road plans were completed several years ago while the Eldorado Parkway plans are currently under design. However, we are in discussions with TxDOT to try to get the second left-turn lane added now while they are working on the intersection. If TxDOT agrees to this, the second left-turn lane will be added by the time the Preston Road project is completed. If not, the second left-turn will be added as part of the City project that will widen Eldorado Parkway to six lanes from Preston Road to Custer Road (which is currently expected to begin in January).

Having the intersection of Preston and Eldorado open is a huge relief! Thank you for your effort in expediting the project. Why is the left turn signal for turning from northbound Preston to westbound Eldorado restricted to green arrow only. The visibility of southbound Preston traffic is unobstructed. Help us understand why we must sit at the light while Preston traffic streams northward and there is no southbound traffic.

Jim,

I agree with your concern. Our typical practice for locations like this where there are double left-turn is to only allow turns on a green arrow to maximize safety. We are considering making some changes at this location as well as others similar to it to try and lessen the delay. Many times you only get the double left-turn lanes built at very busy intersections. In anticipation of this location becoming a very busy intersection someday, we requested that TxDOT build the extra lanes now instead of some other time in the future. However, since it isnít very busy right now (relatively speaking in comparison to the number of lanes available), it winds up causing more delay as you have noted.

Some agencies will allow what we call protected/permitted (turn on green ball or green arrow) double left turns while most do not because there are safety concerns when two side-by-side cars are both trying to judge whether to take a gap in oncoming traffic. During the late 1990ís here in the Dallas area, there was more widespread use protected/permitted double left-turns but many agencies started to shy away from that use when State Farm was listing the top 10 or 20 worst intersections in the United States. Several of those locations were in the Dallas area and all had high numbers of left turn crashes. Many of those locations also had double left-turn lanes with protected/permissive left-turns. As a result of the safety studies, they were changed to protected only and crashes were reduced.

Once school gets started up next week, we will monitor this location to see how volumes change. We will then look at options of striping out left-turn lanes that maybe arenít needed at this time to help with sight lines. If it appears those changes can be made without further increasing left-turn delays, we can then likely have some or all of the left-turn movements become protected/permitted. If our study shows the changes can be implemented, we will get them in place within the next 8 weeks or so.

Thanks

Jim,

Unfortunately we have not been able to finish the analysis yet. The analysis should be complete in less than 2 to 3 weeks. Assuming the analysis shows it is the right thing to do, implementing the changes will likely not occur until early next year as we coordinate our efforts with TxDOT as they finish the intersection improvements at this location.

Thanks
