Engineering high-capacity national and state highway corridors — from GIS-based route planning and DPR to geometric design, pavement engineering, and construction supervision to NHAI and MoRTH standards.
Highway & Road · National & State Highways
National and state highways form the backbone of India's economic mobility, linking cities, ports, and industrial hubs. HRP Infra delivers full-lifecycle highway engineering — combining GIS-driven route selection, robust geometric and pavement design, and rigorous construction supervision aligned with NHAI, MoRTH, and IRC frameworks.
From two-lane state highways to multi-lane access-controlled corridors and expressways, our integrated approach optimises alignment, minimises land acquisition, and ensures long-term structural performance under heavy commercial traffic loads.
What We Deliver
Comprehensive consultancy across every phase of national and state highway development.
GIS, LiDAR, and DGPS-based corridor identification, terrain analysis, and alternative alignment evaluation to select cost-effective, low-impact highway routes.
Traffic surveys, demand forecasting, techno-economic feasibility, and detailed project reports prepared to NHAI and MoRTH documentation standards.
Horizontal and vertical alignment, superelevation, sight distance, interchange and grade-separated junction design as per IRC:73 and IRC:SP:73 norms.
Flexible (IRC:37) and rigid (IRC:58) pavement design, overlay design, and lifecycle cost analysis for high-volume commercial traffic corridors.
Multi-stage road safety audits from design to post-construction, signage and marking schemes, and crash-barrier design per IRC:SP:88 and IRC:35.
Authority Engineer / Independent Engineer services, material testing, quality audits, and milestone-based progress monitoring through to handover.
Our Methodology
Compliance Framework
Every national and state highway project is engineered in strict accordance with the governing Indian codes, ministry specifications, and authority guidelines.
Material, workmanship, and construction specifications for road and bridge works.
Project preparation, DPR, and supervision frameworks for national corridors.
Indian Roads Congress codes governing highway geometry and capacity.
Standards for flexible and rigid pavement design and rehabilitation.
Guidelines for safety audits, traffic signs, markings, and barriers.
Codes covering highway drainage, cross-drainage, and bridge loading.
HRP Infra continually updates its design practice to reflect the latest revisions of all IRC, MoRTH, and NHAI publications, along with applicable IS codes and state PWD specifications.
