Can anyone tell me when traffic on Custer will be opened and flowing normally (at least on north and south bound Custer) at 121. They poured the north bound permanent pavement under the overpass a few weeks ago, but it has yet to open to traffic. With all the other construction on 121 it would be a great help to at least have this intersection opened up now that it appears ready to go. Thanks.

Mike C.: after receiving your Message Board question on Friday, I scheduled a meeting for this afternoon with TxDOT not only to ask about the construction of the Custer intersection, but all of the other intersections as well. Custer was scheduled to be opened tonight allowing 3 lanes of traffic in each direction. The City and TxDOT are meeting weekly for the remainder of the project in order to improve communication to motorists. We will be sending out email bulletins on a weekly basis to inform motorists of the upcoming changes in the construction phasing. If you or others would like to be added to this email distribution, please contact Stephanie Spence at sspence@friscotexas.gov or 972-335-5585 x138. If you have additional questions, please feel free to contact me directly at the same telephone number extension 100.

Did they update the timelines for the other intersections?

Brian - this is my understanding of TxDOT's schedule. I have forwarded this to them to verify my dates.

Coit The City of Frisco has worked with the City of Plano to improve the signal timing for this location. Plano modified the signal timing at this location today. The traffic is scheduled to be relocated to the newly constructed pavement on September 6, 2005 along Coit. The full intersection is anticipated to be open by September 30th.

Custer the full intersection of Custer should have opened yesterday by the TxDOT contractor allowing for 3 lanes of traffic in each direction.

Hillcrest The full interchange at SH 121 & Hillcrest is scheduled to be bid in September 2006. TxDOT has schedule to switch traffic to the west side of Hillcrest by the end of September or early October and then will begin to build the east side of Hillcrest.

Independence CoServe is finishing their utility relocations this week. The TxDOT contractor will start building the west side of Independence next week. TxDOT anticipates this work to be complete within a couple of months.

Legacy TxDOT changed traffic at the service roads this weekend. They also have added video detection for the traffic signal at this location to provide improved signal timing during non-peak hours.

Ohio The overpass is scheduled to be bid in September 2006. The interim improvements for Ohio northbound and southbound will be fully operational and open to traffic is scheduled for September 16th. At that time, there will be 2 lanes southbound for through traffic and 1 lane southbound for left turning vehicles.

Preston Mall Road A traffic signal was removed this week in order to construct the Preston Road overpass over SH 121. The ultimate configuration of the overpass will allow for 2 lanes of traffic for northbound and 2 lanes of traffic southbound as well as 2 lanes in each direction for a new service road to be built at-grade along Preston.

Service Roads the full service roads will be open to traffic from SH 280 to US 75 after the first of the year.

I am waiting on a few dates I don't have this is my understanding of the current scheduling of the project at the intersections. Please let me know if you have other questions.

I have had a couple of questions from my previous posting I would like to explain. When motorists have to stop at a traffic signal you can get about 600-700 cars per hour per lane through the traffic signal. When traffic is free flowing not stopping at a signal you can get from 1800-2300 cars per hour per lane. The 4 total lanes of the Preston Overpass actually will significantly improve the capacity since you aren't having to sit at a traffic signal.

An example you could think of would be the intersection of the Dallas Parkway/Dallas North Tollway/SH 121. Traffic on SH 121 doesn't stop and neither does the tollroad. There is minimum traffic left in the at-grade intersection underneath. That traffic is primarily turning movement traffic. This intersection is very similar to the intersection that will be constructed at Preston only that Preston will be the middle level of the interchange not SH 121. Hope that helps explain my earlier posting. Let me know if you need further clarification.
