DCMP 10 15 2011

All of the trackwork in the junction is in place. Inbound junction turnout 07 16, 17 2011 outbound turnout 07 23, 24 2011. The double crossover to the east was installed 09 03, 05 2011. Third rail has been installed from the junction west to the west end of the flyover on outbound track N2 and several hundred feet short on track N1. Looks like all of the train control ground equipment for double crossover and on the K route tracks through the junction are in place. Those that are being used are connect to the West Falls Church K06 train control room. The contractor building the new K98 junction train control room next to the Fisher Avenue substation were working on the foundation for the building. Funny how all of the track work and related ground equipment for the junction is in place with nothing to connect it to.

Lifting gantry #1 is now working west of Capitol One Drive in the Tysons East (McLean) station. The gantry is positioned between the trackways over the center of the columns supporting the elevated structure at the west end of the station. It is still working the trackway spans through the station. Only 4 spans are left to be assembled, 2 on each track. The steel for the mezzanine is in place. About 2/3 of the concrete beams for the station platform are in place.

Most of the spans in the Tysons East (McLean) and Tysons Central 123 (Tysons Corner) stations were assembled on the ground and lifted into place with a crane.

Lifting gantry #2 is now working west of Gosnell Road / Westpark Drive. It crawled over the intersection of Leesburg Pike and Gosnell Road / Westpark Drive as those spans have fixed bearings similar to the spans over the Capitol Beltway VA I-495 and are being assembled using a crane.

Only a hand full of segments need to be set in the spans over the Gosnall / WestPark Leesburg Pike intersection, outbound track N2 4, inbound track N1 2 east of the intersection, 4 outbound track N2, 3 inbound track N1 west of the intersection and 5 outbound track N2, 3 inbound track N1 over the intersection.

Lifting gantry #3 broke down in late June after completing most of the spans for inbound track N1. It was inactive until July when it was put back service and completed the remainder spans. It was moved over to outbound track N2 and set several segments of the span over the interloop of the Capitol Beltway VA I-495 before breaking down again in August. It has been disassembled and removed from the site and the remainder of the spans are being assembled by conventional means using one of the tracked cranes.

It should be noted now that there a total of 16 spans the have fixed bearings. The spans over Capitol Beltway VA I-495 are continuious units composed of 5 spans that have 2 fixed bearings and 2 expansion bearings. The spans over the Leesburg Pike and Gosnell Road / Westpark Drive intersection are continuious units composed of 3 spans on 2 fixed bearings. The spans from the straddle bent over the Dulles Access Road to the median of the Dulles Access Road west of Leesburg Pike VA-7 are continuious units composed of 2 spans on 1 fixed bearing. The remander of the spans, including the spans in the elevated stations, are single unit spans bearing on 2 columns or on 1 column and 1 abutment.

The concrete beams for the station platform in the (Tysons Central 123) Tysons Corner station are only done from the west end of the station to the east side of Tysons Boulevard. The contractor has begun clearing the area at Tysons Corner Ring Road and Tysons Boulevard for the station entrance and pedestrian bridge on the south side Chain Bridge Road that will connect the mall to the station.

The cut and cover tunnels from the bored tunnel east of the Tysons Central 7 (Greensboro) station are almost complete. Only one segment of the platform slab at the west end remains to be poured, the next to last segment was poured early that morning.

The straddle bent over eastbound Leesburg Pike still has the forms in place. All of the column west of the Leesburg Pike straddle bent and straddle bents over the Dulles Access and Toll Road are done The column west of the straddle bent over the Dulles Access Road is a cantilever span column. The footings west of the abutment are being readied for the retaining walls.

Most of the barrier walls between Leesburg Pike and Wiehle are in place. Most of the places where they are not in place is where ground work for the traction power conduits is being installed from the substation and at the interlockings.

Structural work at Wiehle Avenue is done. Precast concrete panels for the station facade have been delivered. The first one was set at the east end of the station on the north outbound side. The architectural design, texture and color of the panels bares no resemblance to the station renderings. In my opinion what being installed looks better then what is shown in those rendering. The dispatcher office at the west end of the platform has the same texture and color as the precast concrete facade panels.

For those that own a Nikon DSLR, file names roll over to DXX_0001.* after DXX_9999.* .
