The PLUS north-south highway is patterned after the U.S. highway but inept in more ways:
1) The job is never done, the road is always under repair at one or more section(s). Does this means that the initial work substandard?;
2) In the US there are few tolls unlike PLUS;
3) The toll rates keep on increasing partly because of the signed contract and partly due to inefficiency and repair works. Pass the buck to the motorists!;
4) In several cases the road signage are inconsistent, inaccurate, or too many;
5) Too many guard rails along the shoulder when they are not actually necessary. Overdoing it may be a source of danger and cause more harm than good;
6) Landscaping a roadway is not like that of a garden e.g. the plants should be hardy and of less maintenance. To reduce further costs topiary should be minimised;
7) Is it important to mark every 100m distance? The more posts placed along the shoulder or divider railings the more chance they become flying missiles during accidents.
8) All in all the safety margins of the PLUS highway are quite narrow as such that when accidents occur they are often fatal. In the U.S., the divider is wide and grassy with little or no metal railings;
9) PLUS wants to go electronic toll payment all the way. Just because the technology is there they think of saving a meagre sum and get rid of some low level employment of toll counters. It is better to keep at least one manual toll should at each exit point for convenience and service to motorists when problems of any nature arise.
When people are 'giving' money to PLUS yet they want to make it hassle!
PLUS should learn from the Romans. More than 2000 years ago they showed us how to build roads, the Appian Way or Via Appia.
A section of the Appian Way, famous Roman military road which is still usable after 2000 years.
Sheep grazing across an ancient road on the outskirt of Rome. This road was an elaborate network of others like it, once linked the capital with the rest of the empire.
Via Appia, first of the great Roman roads, was begun in 312 B.C. It reached southwards 360 miles from Rome to Brundisium.
p.s. My experience driving on U.S roads was almost 10 years.
