Question: Where does the motorway end that runs south of Preston through the junction of M6 and another North West England motorway?

Context paragraphs:
M5 motorway: The M5 is a motorway in England linking the Midlands and the South West.  It runs from Junction 8 of the M6 at West Bromwich near Birmingham to Exeter in Devon.  Heading south-west, the M5 runs east of West Bromwich and west of Birmingham through Sandwell Valley.  It continues past Bromsgrove (and from Birmingham and Bromsgrove is part of the Birmingham Motorway Box), Droitwich Spa, Worcester, Tewkesbury, Cheltenham, Gloucester, Bristol, Weston-super-Mare, Bridgwater and Taunton on its way to Exeter, ending at Junction 31.  It is the primary gateway to South West England.  Congestion is common during the summer holidays, on Friday afternoons, and school and bank holidays on the section south of the M4.

M6 motorway (Ireland): The M6 motorway (Irish: "Mótarbhealach M6" ) is a motorway in Ireland, which runs (together with the M4) from Dublin to Galway.  The M6 extends from its junction with the M4 at Kinnegad all the way west to the outskirts of Galway City, but the Athlone bypass and the approach to Galway city - while of dual carriageway standard - have not been designated motorway and are still signed as N6.  The motorway was officially completed and opened to traffic on 18 December 2009, and was the first city-to-city direct major inter-urban route to be completed in Ireland.  The M6 and M4, which form the Galway-Dublin route, consist of a grade-separated 2+2 dual carriageway road with a top speed limit of 120 km/h.  At approximately 144 km (90 mi), the M6 is the third longest motorway in the state.

Preston Patrick: Preston Patrick is a village and civil parish in South Lakeland, Cumbria, England.  It has junction 36 of the M6 motorway in its south west corner and extends north east on both sides of the motorway until just beyond the B2564 road.  In the 2011 census its population was reported to be 426.  The neighbouring parishes are Old Hutton and Holmescales to the north, Lupton to the east, Beetham to the south and Preston Richard to the west.

James Drake (engineer): Sir James Drake CBE (27 July 1907 – 1 February 1989) was a chartered civil engineer who is regarded as the pioneer of the national motorway network in the United Kingdom.  As the County Surveyor and Bridgemaster of Lancashire County Council from 1945 to 1972 he led teams that designed the first stretch of motorway opened to the public, the Preston By-pass (now the M6 from Junctions 29 to 32) on 5 December 1958.  There then followed numerous contracts to extend the motorway in the north west of England, which, thanks to his role, probably still has the greatest density of motorways in the country.  He was appointed a CBE in 1962 for his services as County Surveyor and Bridgemaster of Lancashire County Council and in 1973 he was knighted in recognition of his role as head of the North West Road Construction Unit and the Lancashire Sub-Unit, organisations that further extended his initial work.

Nashville Terminal Subdivision: The Nashville Terminal Subdivision is a railroad line owned by CSX Transportation in the U.S. State of Tennessee.  The Subdivision is broken up into 5 sections all in Nashville, Tennessee.  The northern part of the Terminal is in Madison, Tennessee at milepost 000/0BA 174 on the southern end of the Ex-L&N Mainline Subdivision at Monfort.  Disptach for the Mainline Sub is known as "LD" which is part of the Cincinnati Division.  From here in Madison begins the double track that stays for another 22 miles south to Brentwood, Tennessee.  At milepost 000/0BA/00H 176.6, the famous Johnny Cash "Amqui" location where the Ex-L&N Evansville, Indiana line, the Henderson Subdivision meets with the Terminal.  Dispatch for the Henderson Sub is known as "SA" and operates on AAR58.  There are two crossings near each other, Williams Ave and Nesbitt Lane at Amqui.  From here the Terminal goes south about 2 miles to the Nashville National Cemetery to the first major location, known as Ekin, 000179, where there is a cross over track from number 1 to number 2 track (left to right track).  There is also the first EDD (Defect Detector) at 000179.1.  Few more miles southward, the next major location appears.  At 000181.0, Maplewood is a major location for the Terminal.  From here the regular Terminal goes south to swap crews at Kayne Ave, and the right side, Radnor Cutoff, detours the city and gives yard departures and arrivals direct access to and from Radnor yard to cities like Louisville and Chicago.  The Cutoff runs from Maplewood to Shelby Park double track.  From Shebly the track converges into one to pass the historic Shelby bridge, then it opens back to double track.  From there, the cutoff hits the Intermediates at 0BA187.0 known as Chicken Pike.  The Radnor Cutoff carries the L&N mainline classification of "0BA" but meets the main at the same milepost from the Terminal.  At Chicken Pike, trains are staged to await arrival to Radnor yard.  Once they get clearance, speed is decreased to 15, and at 0BA188.1 the EDD (Defect Detector) sounds for departures and arrivals.  This location is known as North Radnor.  The right track diverging from the #2 is known as A-1, it is for departure trains to Chattanooga and Atlanta.  The left track which goes west from the #1 is known as A-2, and serves as a departure track to Memphis, and if the cutoff is out of service, all northbound departures.  The interesting piece of Maplewood is the crossovers that are there to move trains from the Cutoff to the Main.  Both lines remain double track for a while.  The main runs south for 2 more miles until the Intermediate signals at 000183.0.  Commonly trains will stop before Delmas Ave when Kayne Ave is at capacity and await dispatch permission before moving south.  From here, the main continues south until the CR Cumberland River Swingbridge, where the main converges into a single track shortly to cross the bridge.  At this point, trains had been running at track speed of around 40.  From the drawbridge into town, speed is reduced to around 10.  After the bridge is passed, the main returns to double track in downtown.  On the #1 track about a half a mile south, another connecting track is present.  This is the Wye track that connects the main with the Bruceton side, while rarely used for mainline trains, locals and river jobs use it.  The location is known as 8th Avenue or 8th Avenue Wye.  The main then runs down to Kayne Ave, the central hotbed of all Nashville thru traffic.  The Memphis, Tennessee Ex-L&N Bruceton Subdivision meets with the Terminal.  The Bruceton Sub begins at Church Street at 00N0.0.  The line then runs single track until 00N0.7 "11th Avenue" where it turns into double track and also meets the aforementioned, Wye track.  The Bruceton line then goes southwest a while to the next signals, at "Shops".  Now speed has been increased.  The line is still double track until "Sellars", where speed is increased to 40 and jurisdiction transferred to the SD Dispatcher.  For a short time, 4 main tracks are present and an additional fifth track for switchers and yard movements.  The tracks from left to right in Kayne Ave are as follows: 100, 99, 98, 12, 3.  The Kayne Ave yard is also here in this area, which houses some frieght and some switcher engines.  The tracks to the old shed are covered and removed.  The Union Station is not an active station, but a historic hotel.  Crew change usually occurs at the "walkway" which is under the Demombreun St bridge by the Kayne Ave Tower.  This is also where the Ex-NC&StL Chattanooga Subdivision begins.  Then tracks run south to Fogg St/South End where things get complicated.  At milepost 000/0BA/00J187 the 98 track merges into the 12 track, making for 3 tracks now.  There is a crossover from 99 to 12, also a crossover from 12 to 3.  About 2/10ths of a mile down the 99 merges into the 12 track reducing the tracks back to the regular double.  About 4/10ths of a mile down the line from Fogg St, 000187.4, Oak St, is a crossover track from #2 to #1 (the track names are no longer 3 and 12, but are back to regular names).  When trains use this crossover northbound, such as Memphis bound trains from the A-2 line, they refer to it as "Long Lead".  And now, the Terminal splits into two parts.  The right side turns into a single track shortly, and will become the Chattanooga Subdivision, and the left side runs south to Brentwood.  The right track runs single shortly until double track for a while.  This begins part of the Chattanooga Sub or J-Line.  The #2 meets with the A-2 connection track at 00J2.2 known as A-2.  Speed is now increased to 40.  Commonly northbounds will stage at 4th Ave on the #1 to await clearance.  Now about a mile down the #1 meets the A-1 connection line.  At 00J3.6 known as A-1.  Further down the double track ends at Glencliff (00J4.9).  Now it runs single for three miles until it hits Danley, which has the D Line connection track, which is an arrival track for incoming Radnor trains from the J Line.  At Danley, the Terminal ends but the same dispatcher handles traffic, "SC".  At Oak Street, our main terminal line goes south two miles to 000189.0 known as Criaghead or Vine Hill.  There is a crossover here from #1 to #2 track.  And there is also a connection/delivery track to the Nashville and Eastern Railroad which connects the Tennessee Central Railroad Museum to a major railroad.  Trains sometimes stop on the #2 before Craighead if they are waiting to enter Radnor yard.  Sometimes trains wait on the #1 at the Berry Road crossing if they await arrival to Kayne Ave. At this point, speed has been increased to 30 from 10.  Moving south, the line hits Radnor Yard at 000192.  The #2 track meets the E-Line arrival track which most Memphis trains and locals use.  The B-Line which meets the #1 track is used for departures out of the C yard and local jobs.  At Mayton, 000192.3, the B line meets the #1 track, and there is a crossover track from #2 to #1.  Speed is now at 40.  2 miles south, at 000194.0, South Radnor, the next intersection is present.  This is where the Radnor A yard meets the main.  There is a single departure/arrival track that meets the #2 track along with a crossover from #1 to #2 track.  Commonly, the #2 track south of the signals is used to halt trains.  This location is known as TVA, because of the power station that is adjacent.  From here the Terminal runs about 2.5 miles south until we hit the southern tip.  The tracks converge onto one single main, at 000/0BA196.6 known as Brentwood.  Speed is increased to 50 and jurisdiction to the S.E. dispatcher.  The right track is the main, S&NA North, while the left track is the Nashville Subdivision which runs to Columbia and exchanges freight with the TSRR.  The Nashville Terminal Subdivision is one of the busiest locations on the CSX network, and one of the most important.

A601(M) motorway: The A601(M) is a motorway in Lancashire, England.  It is 1.3 mi long, and meets the M6 at Junction 35.  It is a unique motorway within the United Kingdom as it has a dual carriageway section leading north from Junction 35 of the M6, with a single carriageway section (the only single carriageway section with motorway status in the United Kingdom) leading south, where it terminates at a T junction on a B road.  The A601(M) is not the A601 under motorway restrictions, as is the usual explanation for such a classification in the UK.  The A601 itself is the Derby inner ring road, over 100 mi away.

A7 road (Great Britain): The A7 is a major trunk road in the United Kingdom, that runs south from Edinburgh in Central Scotland to Carlisle in North West England.  The A7 meets the M6 motorway close to Carlisle, which runs south to the north west, Midlands and south of England.  However, the A702 road, which runs further to the north east, and the A74 (M) south, provide a quicker alternative and serve as the main link between Edinburgh and the M6.

M61 motorway: The M61 is a motorway in North West England.  It runs from the M60 motorway northwest of Manchester and heads northwest past Bolton and Chorley to join the M6 just north of the junction between the M6 and M65 motorways to the south of Preston.

M23 motorway: The M23 is a motorway in the United Kingdom.  The motorway runs from south of Hooley in Surrey, where it splits from the A23, to Pease Pottage, south of Crawley in West Sussex where it rejoins the A23.  The northern end of the motorway starts at junction 7 on what is effectively a 2 mi spur north from junction 7 of the M25 motorway (junction 8 on the M23).  From Hooley it runs for 17 mi past Redhill, Gatwick Airport and Crawley.  A spur runs from junction 9 to Gatwick Airport.

M65 motorway: The M65 is a motorway in Lancashire, England.  It runs from just south of Preston through the major junction of the M6 and M61 motorways, east past Darwen, Blackburn, Accrington, Burnley, Nelson and ends at Colne.
