When Route 100 was 
built in phases starting in the 1970s until its completion in 1999, it 
was never meant to be an entire loop. In fact, the reason that Route 100
 is located where it is is because the land had been reserved for the 
Outer Beltway and all the State wanted to build was a highway link 
between Route 29 in Ellicott City and Mountain Road in Pasadena to ease 
congestion in rapidly growing areas of Howard and Anne Arundel Counties.
 Route 100 did just that except that it opened the floodgates for more 
growth and sprawl which put congestion of roads back to where it was 
before Route 100 and then some. Given that Route 100 follows the 
southern right of way set aside for the Outer Beltway, hows about we 
extend it in both directions to complete the loop and give Baltimore two
 Beltways just the Eisenhower Era Interstate Planners had intended. 
The
 moniker of Route 100 will be dropped in place of the more fitting 
I-595. I realize this is the unsigned name of a stretch of Route 301/50 
but I think our new Outer Beltway is more deserving of this noble title.
 We will start our journey at the eastern end of Route 100(now known as 
I-595) in Pasadena. Route 100/I-595 ends at Mountain Road currently but 
it will be extended as I-595 east of Mountain Road which will have a 
grade separated interchange as will all of its crossings. It will 
continue eastbound before crossing the bay between Bodkin Creek and Boyd
 Pond. This long bridge will do something unheard of; connect Pasadena 
in Anne Arundel County and Joppatowne in Harford County.  
This
 bridge, which gives all other bridges a run for their money, will end 
at Canal Creek in just south of Joppatowne. Extending Eastern Avenue to 
meet I-595 should be considered. There is some relatively unused land 
here which I-595 can use for interchanges with Route 40 (Pulaski 
Highway), Philadelphia Road, and I-95. It may be a good idea for I-95 
and Philadelphia Road to share ramps to one another a la Park Heights 
Avenue and Stevenson Road given how closely parallel the roads run in 
between each other. After its interchange with I-95, I-595 will meet up 
with Route 1 (Belair Road) in between Perry Hall and Kingsville. After 
unceremonious interchanges with Harford Road, Glen Arm Road, and Manor 
Road, I-595 will cross Loch Raven Reservoir. After this, things begin to
 get interesting.
In Central and western 
Baltimore County, there are a few roads that already exist that I've 
noticed could be spurs for the Outer Beltway. After an interchange with 
Route 146 (Dulaney Valley Road) I-595 will follow what is now Old Bosley
 Road albeit much wider and up to Interstate Standards after which it 
will roughly follow Bosley Road and finally Warren Road. Warren Road was
 one of the Roads I had considered to be a spur for the Outer Beltway 
therefore I'm using it as such. Given the Residential nature of these 
Neighborhoods, there will be no interchanges until meeting Route 45 
(York Road) The existing at-grade intersection will be upgraded to a 
clover leaf and Warren Road, currently a two to four lane road separated
 by a median strip will become I-595, a six lane divided Interstate. 
West
 of York Road I-595, the continue to follow the Warren Road Route. Here,
 it will be much easier to transform the road as it has more of a 
highway-esque layout. Warren Road ends with an interchange with I-83. 
I-595 will continue on west of I-83. It will meet Route 25 (Falls Road) 
and take the path of least resistance through the Greenspring Valley 
with interchanges at Greenpsring Avenue and Park Heights Avenue just 
below the Caves Valley Country Club.
I have 
setup I-595 to be level with Owings Mills Boulevard right where it veers
 north and follows the CSX lines. Why? Because I believe Owings Mills 
Boulevard between Winans Road and Stevenson University is the other 
"spur" of the Outer Beltway is. Owings Mills Boulevard has an 
interchange with I-795 here and its intersections with Reisterstown 
Road, Red Run Boulevard, Lakeside, Boulevard, Lyons Mill Road, and 
Winans Road will be upgraded to grade separated interchanges. Other 
smaller streets that meet up with Owings Mills Boulevard/I-595 will have
 bridges over or under them without access. The planned extension of 
Owings Mills Boulevard to Liberty Road will also be a grade separated 
interchange. 
Once I-595 has crossed Liberty 
Road, it will take curvy path of least resistance. That simply means 
that it will curve around to ensure the fewest number of homes have to 
be destroyed to construct it. Eventually it will cross into Howard 
County and will cross Route 99 at its current signalized intersection 
with Route 29. Route 29 between Route 100 and its northern terminus at 
Route 99 has served as a southwestern spur of the Outer Beltway (I-595) 
Route 29 between Route 99 and Route 100 will be re-dubbed I-595 and the 
traffic light intersection at Route 99 will be upgraded to a grade 
separated interchange. I-595, once it has completed its short stint 
using the current Route 29 will make an easterly turn back to the 
current Route 100. At this point the circle is complete.
Now
 that I have completed my entire series on un-built Freeways in 
Baltimore I bet I know what you're thinking; That was stupid. Yes, yes 
it was however we must revisit these failed attempts now and then to 
remind ourselves why they failed in the first place so history isn't 
doomed to repeat itself. Building anyone of these Freeways would be a 
waste of Tax Payer Money, have to unnecessarily relocate hundreds if not
 thousands, will ruin sought after park lands, will pollute the air as 
well as the water, and will do nothing to actually reduce roadway 
congestion.
