Change in my approach of packaging the fixes
The total size, even after being archived, still exceeds the server maximum 10MB allowed per download file, resulting in 3 parts. With some feedback that folks are still having trouble with multi-part files, I've separated the fixes out into separate .7z files because there are just too many now. So, I've broken them down into the following sets.

Download ALL 3 .7z files and extract them all into a temporary folder onto your Desktop, then import all the Resources in S3PE by selecting all files (Ctrl+A).


Notes & Changelog:
As and when I get reports of any issues, or new spots, or patch changes (if any).

• Oct 18, 2011 update:
  • Compatible with patch 1.26.89. Would most likely be compatible with any patches in the future as well.
  • If you had renamed the modified worlds to *.fixed before patching (or installing new add-on), you can simply renamed the pair of them back to *.orig and .world respectively, as the Wiki instructions state
• Oct 03, 2011 update:
  • I've decided to pull the BridgeportSmoothenRoadGrading.7z as my CAW work files have been having problems being saved after this last change, and EIG no longer work with this version (apparently is only a one-time dealie kinda thing, which explains all the do-overs). Playing on them is fine, however (at least it is in my setup, but I don't know how it would play out in a Save game after a few weeks/months Sims time). So, until I figured out what CAW doesn't like about these Lots (most are the ones with the stubborn minor Lot tears), I think it safer not to distribute them. To the 3 people that had downloaded them, sorry! Perhaps you'd like to reimport the other 2 7z files in the original Bridgeport.world file over again, just to be safe. Again, I apologize for the inconvenience.
• Oct 02, 2011 update:
  • There are now more yellow spots with additional areas I had missed on the first upload, from feedback from folks in the comments (or via PMs) like Menaceman44 and folks at various forums with CAW sections including CustomSims3, builders.forumotion.net and @BBS, where I normally lurk.
  • There is also new light-blue spots, denoting areas where roads have been regraded and smoothen a tad. I didn't go overboard with this as my first pass produced Lot tears, so I started over from scratch (probably a total of 3 times, 5 if counting CAW not saving and crashing. Well, I've actually stopped counting the do-overs). This is as good as I know how to make it. If there are still Lot tears I missed, don't hesitate to shout out in comments.
  • As with Twinbrook, I also made the following changes in addition to rechecking Routing and Regrading roads:
    1. Removed any non-routable terrain painting that was touching roads to ensure the routing encompass the road surface
    2. Pushed any railings located on curves back a tad so the non-routable terrain painting can be pulled back
  • Finally, decided to remove ALL roads to finally put that double-road placement rumor to bed (I believe now it is simply a mistaken assumption of the terrain paints in the Downtown area that look a lot like the Road textures, again if somebody has proof to refute this I welcome images or links to the findings), even though I claimed I won't ever do it. Yeah, never say never. So, in doing this, I found some blue spots under the roads similar to the one found in WA as mentioned in post #24, but no double-placed roads anywhere. These (the blue spots under roads) have been corrected as well.
  • The new approach as detailed above now produced 3 .7z files, containing a total of 800 608(2+606+192) items.
  • Resource Types modified broken down by each 7z file as detailed below:
    • BridgeportFixedRouting.7z containing 2 files
      1. 0x05CD4BB3 UNKN World Routing
      2. 0x05DA8AF6 UNKN World boundaries
    • BridgeportFixedRoadIntersections.7z containing 606 files
      1. 0x9063660E UNKN World Roads & Walkways
      2. 0x00B2D882 0x00000001 _IMG DDS Image
      3. 0x01661233 0x00000002 MODL scene Object Model (aka Object Geometry)
    • BridgeportSmoothenRoadGrading.7z containing 192 files
      1. 0x033B2B66 UNKN ?? World Model/Geometry/Terrain/Height map info ??
      2. 0xAE39399F UNKN World geometry
• The .7z file contains 608 items.
• Compatible with all patch levels up to the current 1.24 (as of Jul 26, 2011).
• Would conflict with any other download that make changes to the .world file that changed the above named resources.

What is this?
This is in the same vein as the WA routing fixes available here, but this time for Bridgeport.

What has been done?
As explained in the wiki linked below,

• the yellow spots denote areas where the Sim non-routable and Camera non-routable painting have been repainted over blank spots. This includes at the world edges, too, although it may not be denoted on the image
• the red spots denote areas where the intersections have been corrected so that the Intersection and Road pieces now all connect.
• There is a visual way to tell if fix has been applied.
  • Look at the spots denoted by Red dot - at a road intersection. If you can see the intersections are white (instead of yellow) from Map View, the fix is applied correctly.

Backup!
Heed that backup instructions, really! You've been warned!


How to install?
Please be sure to read and follow the instructions under "Edit in S3PE" in full in Game Help:World Routing Lags^wiki
The rest of the info is the same, pretty standard - backup, read and follow instructions to the letter, provide feedback, etc etc. All is in the wiki - READ it!


How to remove or restore the file before updating?

• Go to this path
  Code:

  \Program Files (x86)\Electronic Arts\The Sims 3 Late Night\GameData\Shared\NonPackaged\Worlds\

• Delete the *.world file. Or if you want to reuse it after patching, rename it with a ".fixed" extension, so the filename becomes "Bridgeport.world.fixed"
• Rename the "*.orig" copy by removing the .orig extension (or from whatever you have renamed it to).
• Delete caches before starting game. Game Help:Sims 3 Delete Cache Files^wiki

Feedback
As always, feedback is welcomed.
Please report any other areas that you get stuck Sims at that I might have missed. If I may have been overzealous in the corrections.
